Quoting Smithsonian National Air and Space Museum | Boeing B-29 Superfortress "Enola Gay":

Boeing’s B-29 Superfortress was the most sophisticated propeller-driven bomber of World War II and the first bomber to house its crew in pressurized compartments. Although designed to fight in the European theater, the B-29 found its niche on the other side of the globe. In the Pacific, B-29s delivered a variety of aerial weapons: conventional bombs, incendiary bombs, mines, and two nuclear weapons.

On August 6, 1945, this Martin-built B-29-45-MO dropped the first atomic weapon used in combat on Hiroshima, Japan. Three days later, Bockscar (on display at the U.S. Air Force Museum near Dayton, Ohio) dropped a second atomic bomb on Nagasaki, Japan. Enola Gay flew as the advance weather reconnaissance aircraft that day. A third B-29, The Great Artiste, flew as an observation aircraft on both missions.

Details, quoting from Smithsonian National Air and Space Museum | Lockheed P-38J-10-LO Lightning

In the P-38 Lockheed engineer Clarence "Kelly" Johnson and his team of designers created one of the most successful twin-engine fighters ever flown by any nation. From 1942 to 1945, U. S. Army Air Forces pilots flew P-38s over Europe, the Mediterranean, and the Pacific, and from the frozen Aleutian Islands to the sun-baked deserts of North Africa. Lightning pilots in the Pacific theater downed more Japanese aircraft than pilots flying any other Allied warplane.

Maj. Richard I. Bong, America’s leading fighter ace, flew this P-38J-10-LO on April 16, 1945, at Wright Field, Ohio, to evaluate an experimental method of interconnecting the movement of the throttle and propeller control levers. However, his right engine exploded in flight before he could conduct the experiment.

Long Description:
From 1942 to 1945, the thunder of P-38 Lightnings was heard around the world. U. S. Army pilots flew the P-38 over Europe, the Mediterranean, and the Pacific; from the frozen Aleutian Islands to the sun-baked deserts of North Africa. Measured by success in combat, Lockheed engineer Clarence "Kelly" Johnson and a team of designers created the most successful twin-engine fighter ever flown by any nation. In the Pacific Theater, Lightning pilots downed more Japanese aircraft than pilots flying any other Army Air Forces warplane.

Johnson and his team conceived this twin-engine, single-pilot fighter airplane in 1936 and the Army Air Corps authorized the firm to build it in June 1937. Lockheed finished constructing the prototype XP-38 and delivered it to the Air Corps on New Year’s Day, 1939. Air Corps test pilot and P-38 project officer, Lt. Benjamin S. Kelsey, first flew the aircraft on January 27. Losing this prototype in a crash at Mitchel Field, New York, with Kelsey at the controls, did not deter the Air Corps from ordering 13 YP-38s for service testing on April 27. Kelsey survived the crash and remained an important part of the Lightning program. Before the airplane could be declared ready for combat, Lockheed had to block the effects of high-speed aerodynamic compressibility and tail buffeting, and solve other problems discovered during the service tests.

The most vexing difficulty was the loss of control in a dive caused by aerodynamic compressibility. During late spring 1941, Air Corps Major Signa A. Gilke encountered serious trouble while diving his Lightning at high-speed from an altitude of 9,120 m (30,000 ft). When he reached an indicated airspeed of about 515 kph (320 mph), the airplane’s tail began to shake violently and the nose dropped until the dive was almost vertical. Signa recovered and landed safely and the tail buffet problem was soon resolved after Lockheed installed new fillets to improve airflow where the cockpit gondola joined the wing center section. Seventeen months passed before engineers began to determine what caused the Lightning’s nose to drop. They tested a scale model P-38 in the Ames Laboratory wind tunnel operated by the NACA (National Advisory Committee for Aeronautics) and found that shock waves formed when airflow over the wing leading edges reached transonic speeds. The nose drop and loss of control was never fully remedied but Lockheed installed dive recovery flaps under each wing in 1944. These devices slowed the P-38 enough to allow the pilot to maintain control when diving at high-speed.

Just as the development of the North American P-51 Mustang, Republic P-47 Thunderbolt, and the Vought F4U Corsair (see NASM collection for these aircraft) pushed the limits of aircraft performance into unexplored territory, so too did P-38 development. The type of aircraft envisioned by the Lockheed design team and Air Corps strategists in 1937 did not appear until June 1944. This protracted shakedown period mirrors the tribulations suffered by Vought in sorting out the many technical problems that kept F4U Corsairs off U. S. Navy carrier decks until the end of 1944.

Lockheed’s efforts to trouble-shoot various problems with the design also delayed high-rate, mass production. When Japan attacked Pearl Harbor, the company had delivered only 69 Lightnings to the Army. Production steadily increased and at its peak in 1944, 22 sub-contractors built various Lightning components and shipped them to Burbank, California, for final assembly. Consolidated-Vultee (Convair) subcontracted to build the wing center section and the firm later became prime manufacturer for 2,000 P-38Ls but that company’s Nashville plant completed only 113 examples of this Lightning model before war’s end. Lockheed and Convair finished 10,038 P-38 aircraft including 500 photo-reconnaissance models. They built more L models, 3,923, than any other version.

To ease control and improve stability, particularly at low speeds, Lockheed equipped all Lightnings, except a batch ordered by Britain, with propellers that counter-rotated. The propeller to the pilot’s left turned counter-clockwise and the propeller to his right turned clockwise, so that one propeller countered the torque and airflow effects generated by the other. The airplane also performed well at high speeds and the definitive P-38L model could make better than 676 kph (420 mph) between 7,600 and 9,120 m (25,000 and 30,000 ft). The design was versatile enough to carry various combinations of bombs, air-to-ground rockets, and external fuel tanks. The multi-engine configuration reduced the Lightning loss-rate to anti-aircraft gunfire during ground attack missions. Single-engine airplanes equipped with power plants cooled by pressurized liquid, such as the North American P-51 Mustang (see NASM collection), were particularly vulnerable. Even a small nick in one coolant line could cause the engine to seize in a matter of minutes.

The first P-38s to reach the Pacific combat theater arrived on April 4, 1942, when a version of the Lightning that carried reconnaissance cameras (designated the F-4), joined the 8th Photographic Squadron based in Australia. This unit launched the first P-38 combat missions over New Guinea and New Britain during April. By May 29, the first 25 P-38s had arrived in Anchorage, Alaska. On August 9, pilots of the 343rd Fighter Group, Eleventh Air Force, flying the P-38E, shot down a pair of Japanese flying boats.

Back in the United States, Army Air Forces leaders tried to control a rumor that Lightnings killed their own pilots. On August 10, 1942, Col. Arthur I. Ennis, Chief of U. S. Army Air Forces Public Relations in Washington, told a fellow officer "… Here’s what the 4th Fighter [training] Command is up against… common rumor out there that the whole West Coast was filled with headless bodies of men who jumped out of P-38s and had their heads cut off by the propellers." Novice Lightning pilots unfamiliar with the correct bailout procedures actually had more to fear from the twin-boom tail, if an emergency dictated taking to the parachute but properly executed, Lightning bailouts were as safe as parachuting from any other high-performance fighter of the day. Misinformation and wild speculation about many new aircraft was rampant during the early War period.

Along with U. S. Navy Grumman F4F Wildcats (see NASM collection) and Curtiss P-40 Warhawks (see NASM collection), Lightnings were the first American fighter airplanes capable of consistently defeating Japanese fighter aircraft. On November 18, men of the 339th Fighter Squadron became the first Lightning pilots to attack Japanese fighters. Flying from Henderson Field on Guadalcanal, they claimed three during a mission to escort Boeing B-17 Flying Fortress bombers (see NASM collection).

On April 18, 1943, fourteen P-38 pilots from the 70th and the 339th Fighter Squadrons, 347th Fighter Group, accomplished one of the most important Lightning missions of the war. American ULTRA cryptanalysts had decoded Japanese messages that revealed the timetable for a visit to the front by the commander of the Imperial Japanese Navy, Admiral Isoroku Yamamoto. This charismatic leader had crafted the plan to attack Pearl Harbor and Allied strategists believed his loss would severely cripple Japanese morale. The P-38 pilots flew 700 km (435 miles) at heights from 3-15 m (10-50 feet) above the ocean to avoid detection. Over the coast of Bougainville, they intercepted a formation of two Mitsubishi G4M BETTY bombers (see NASM collection) carrying the Admiral and his staff, and six Mitsubishi A6M Zero fighters (see NASM collection) providing escort. The Lightning pilots downed both bombers but lost Lt. Ray Hine to a Zero.

In Europe, the first Americans to down a Luftwaffe aircraft were Lt. Elza E. Shahan flying a 27th Fighter Squadron P-38E, and Lt. J. K. Shaffer flying a Curtiss P-40 (see NASM collection) in the 33rd Fighter Squadron. The two flyers shared the destruction of a Focke-Wulf Fw 200C-3 Condor maritime strike aircraft over Iceland on August 14, 1942. Later that month, the 1st fighter group accepted Lightnings and began combat operations from bases in England but this unit soon moved to fight in North Africa. More than a year passed before the P-38 reappeared over Western Europe. While the Lightning was absent, U. S. Army Air Forces strategists had relearned a painful lesson: unescorted bombers cannot operate successfully in the face of determined opposition from enemy fighters. When P-38s returned to England, the primary mission had become long-range bomber escort at ranges of about 805 kms (500 miles) and at altitudes above 6,080 m (20,000 ft).

On October 15, 1943, P-38H pilots in the 55th Fighter Group flew their first combat mission over Europe at a time when the need for long-range escorts was acute. Just the day before, German fighter pilots had destroyed 60 of 291 Eighth Air Force B-17 Flying Fortresses (see NASM collection) during a mission to bomb five ball-bearing plants at Schweinfurt, Germany. No air force could sustain a loss-rate of nearly 20 percent for more than a few missions but these targets lay well beyond the range of available escort fighters (Republic P-47 Thunderbolt, see NASM collection). American war planners hoped the long-range capabilities of the P-38 Lightning could halt this deadly trend, but the very high and very cold environment peculiar to the European air war caused severe power plant and cockpit heating difficulties for the Lightning pilots. The long-range escort problem was not completely solved until the North American P-51 Mustang (see NASM collection) began to arrive in large numbers early in 1944.

Poor cockpit heating in the H and J model Lightnings made flying and fighting at altitudes that frequently approached 12,320 m (40,000 ft) nearly impossible. This was a fundamental design flaw that Kelly Johnson and his team never anticipated when they designed the airplane six years earlier. In his seminal work on the Allison V-1710 engine, Daniel Whitney analyzed in detail other factors that made the P-38 a disappointing airplane in combat over Western Europe.

• Many new and inexperienced pilots arrived in England during December 1943, along with the new J model P-38 Lightning.

• J model rated at 1,600 horsepower vs. 1,425 for earlier H model Lightnings. This power setting required better maintenance between flights. It appears this work was not done in many cases.

• During stateside training, Lightning pilots were taught to fly at high rpm settings and low engine manifold pressure during cruise flight. This was very hard on the engines, and not in keeping with technical directives issued by Allison and Lockheed.

• The quality of fuel in England may have been poor, TEL (tetraethyl lead) fuel additive appeared to condense inside engine induction manifolds, causing detonation (destructive explosion of fuel mixture rather than controlled burning).

• Improved turbo supercharger intercoolers appeared on the J model P-38. These devices greatly reduced manifold temperatures but this encouraged TEL condensation in manifolds during cruise flight and increased spark plug fouling.

Using water injection to minimize detonation might have reduced these engine problems. Both the Republic P-47 Thunderbolt and the North American P-51 Mustang (see NASM collection) were fitted with water injection systems but not the P-38. Lightning pilots continued to fly, despite these handicaps.

During November 1942, two all-Lightning fighter groups, the 1st and the 14th, began operating in North Africa. In the Mediterranean Theater, P-38 pilots flew more sorties than Allied pilots flying any other type of fighter. They claimed 608 enemy a/c destroyed in the air, 123 probably destroyed and 343 damaged, against the loss of 131 Lightnings.

In the war against Japan, the P-38 truly excelled. Combat rarely occurred above 6,080 m (20,000 ft) and the engine and cockpit comfort problems common in Europe never plagued pilots in the Pacific Theater. The Lightning’s excellent range was used to full advantage above the vast expanses of water. In early 1945, Lightning pilots of the 12th Fighter Squadron, 18th Fighter Group, flew a mission that lasted 10 ½ hours and covered more than 3,220 km (2,000 miles). In August, P-38 pilots established the world’s long-distance record for a World War II combat fighter when they flew from the Philippines to the Netherlands East Indies, a distance of 3,703 km (2,300 miles). During early 1944, Lightning pilots in the 475th Fighter Group began the ‘race of aces.’ By March, Lieutenant Colonel Thomas J. Lynch had scored 21 victories before he fell to antiaircraft gunfire while strafing enemy ships. Major Thomas B. McGuire downed 38 Japanese aircraft before he was killed when his P-38 crashed at low altitude in early January 1945. Major Richard I. Bong became America’s highest scoring fighter ace (40 victories) but died in the crash of a Lockheed P-80 (see NASM collection) on August 6, 1945.

Museum records show that Lockheed assigned the construction number 422-2273 to the National Air and Space Museum’s P-38. The Army Air Forces accepted this Lightning as a P-38J-l0-LO on November 6, 1943, and the service identified the airplane with the serial number 42-67762. Recent investigations conducted by a team of specialists at the Paul E. Garber Facility, and Herb Brownstein, a volunteer in the Aeronautics Division at the National Air and Space Museum, have revealed many hitherto unknown aspects to the history of this aircraft.

Brownstein examined NASM files and documents at the National Archives. He discovered that a few days after the Army Air Forces (AAF) accepted this airplane, the Engineering Division at Wright Field in Dayton, Ohio, granted Lockheed permission to convert this P-38 into a two-seat trainer. The firm added a seat behind the pilot to accommodate an instructor who would train civilian pilots in instrument flying techniques. Once trained, these test pilots evaluated new Lightnings fresh off the assembly line.

In a teletype sent by the Engineering Division on March 2, 1944, Brownstein also discovered that this P-38 was released to Colonel Benjamin S. Kelsey from March 3 to April 10, 1944, to conduct special tests. This action was confirmed the following day in a cable from the War Department. This same pilot, then a Lieutenant, flew the XP-38 across the United States in 1939 and survived the crash that destroyed this Lightning at Mitchel Field, New York. In early 1944, Kelsey was assigned to the Eighth Air Force in England and he apparently traveled to the Lockheed factory at Burbank to pick up the P-38. Further information about these tests and Kelsey’s involvement remain an intriguing question.

One of Brownstein’s most important discoveries was a small file rich with information about the NASM Lightning. This file contained a cryptic reference to a "Major Bong" who flew the NASM P-38 on April 16, 1945, at Wright Field. Bong had planned to fly for an hour to evaluate an experimental method of interconnecting the movement of the throttle and propeller control levers. His flight ended after twenty-minutes when "the right engine blew up before I had a chance [to conduct the test]." The curator at the Richard I. Bong Heritage Center confirmed that America’s highest scoring ace made this flight in the NASM P-38 Lightning.

Working in Building 10 at the Paul E. Garber Facility, Rob Mawhinney, Dave Wilson, Wil Lee, Bob Weihrauch, Jim Purton, and Heather Hutton spent several months during the spring and summer of 2001 carefully disassembling, inspecting, and cleaning the NASM Lightning. They found every hardware modification consistent with a model J-25 airplane, not the model J-10 painted in the data block beneath the artifact’s left nose. This fact dovetails perfectly with knowledge uncovered by Brownstein. On April 10, the Engineering Division again cabled Lockheed asking the company to prepare 42-67762 for transfer to Wright Field "in standard configuration." The standard P-38 configuration at that time was the P-38J-25. The work took several weeks and the fighter does not appear on Wright Field records until May 15, 1944. On June 9, the Flight Test Section at Wright Field released the fighter for flight trials aimed at collecting pilot comments on how the airplane handled.

Wright Field’s Aeromedical Laboratory was the next organization involved with this P-38. That unit installed a kit on July 26 that probably measured the force required to move the control wheel left and right to actuate the power-boosted ailerons installed in all Lightnings beginning with version J-25. From August 12-16, the Power Plant Laboratory carried out tests to measure the hydraulic pump temperatures on this Lightning. Then beginning September 16 and lasting about ten days, the Bombing Branch, Armament Laboratory, tested type R-3 fragmentation bomb racks. The work appears to have ended early in December. On June 20, 1945, the AAF Aircraft Distribution Office asked that the Air Technical Service Command transfer the Lightning from Wright Field to Altus Air Force Base, Oklahoma, a temporary holding area for Air Force museum aircraft. The P-38 arrived at the Oklahoma City Air Depot on June 27, 1945, and mechanics prepared the fighter for flyable storage.

Airplane Flight Reports for this Lightning also describe the following activities and movements:

On August 5, 1946, the AAF moved the aircraft to another storage site at the former Consolidated B-24 bomber assembly plant at Park Ridge, Illinois. A short time later, the AAF transferred custody of the Lightning and more than sixty other World War II-era airplanes to the Smithsonian National Air Museum. During the early 1950s, the Air Force moved these airplanes from Park Ridge to the Smithsonian storage site at Suitland, Maryland.

Quoting from Wikipedia | Lockheed P-38 Lightning:

The Lockheed P-38 Lightning was a World War II American fighter aircraft built by Lockheed. Developed to a United States Army Air Corps requirement, the P-38 had distinctive twin booms and a single, central nacelle containing the cockpit and armament. Named "fork-tailed devil" by the Luftwaffe and "two planes, one pilot" by the Japanese, the P-38 was used in a number of roles, including dive bombing, level bombing, ground-attack, photo reconnaissance missions, and extensively as a long-range escort fighter when equipped with drop tanks under its wings.

The P-38 was used most successfully in the Pacific Theater of Operations and the China-Burma-India Theater of Operations as the mount of America’s top aces, Richard Bong (40 victories) and Thomas McGuire (38 victories). In the South West Pacific theater, the P-38 was the primary long-range fighter of United States Army Air Forces until the appearance of large numbers of P-51D Mustangs toward the end of the war. The P-38 was unusually quiet for a fighter, the exhaust muffled by the turbo-superchargers. It was extremely forgiving, and could be mishandled in many ways, but the rate of roll was too slow for it to excel as a dogfighter. The P-38 was the only American fighter aircraft in production throughout American involvement in the war, from Pearl Harbor to Victory over Japan Day.

Variants: Lightning in maturity: P-38J

The P-38J was introduced in August 1943. The turbo-supercharger intercooler system on previous variants had been housed in the leading edges of the wings and had proven vulnerable to combat damage and could burst if the wrong series of controls were mistakenly activated. In the P-38J model, the streamlined engine nacelles of previous Lightnings were changed to fit the intercooler radiator between the oil coolers, forming a "chin" that visually distinguished the J model from its predecessors. While the P-38J used the same V-1710-89/91 engines as the H model, the new core-type intercooler more efficiently lowered intake manifold temperatures and permitted a substantial increase in rated power. The leading edge of the outer wing was fitted with 55 gal (208 l) fuel tanks, filling the space formerly occupied by intercooler tunnels, but these were omitted on early P-38J blocks due to limited availability.

The final 210 J models, designated P-38J-25-LO, alleviated the compressibility problem through the addition of a set of electrically-actuated dive recovery flaps just outboard of the engines on the bottom centerline of the wings. With these improvements, a USAAF pilot reported a dive speed of almost 600 mph (970 km/h), although the indicated air speed was later corrected for compressibility error, and the actual dive speed was lower. Lockheed manufactured over 200 retrofit modification kits to be installed on P-38J-10-LO and J-20-LO already in Europe, but the USAAF C-54 carrying them was shot down by an RAF pilot who mistook the Douglas transport for a German Focke-Wulf Condor. Unfortunately the loss of the kits came during Lockheed test pilot Tony LeVier‘s four-month morale-boosting tour of P-38 bases. Flying a new Lightning named "Snafuperman" modified to full P-38J-25-LO specs at Lockheed’s modification center near Belfast, LeVier captured the pilots’ full attention by routinely performing maneuvers during March 1944 that common Eighth Air Force wisdom held to be suicidal. It proved too little too late because the decision had already been made to re-equip with Mustangs.

The P-38J-25-LO production block also introduced hydraulically-boosted ailerons, one of the first times such a system was fitted to a fighter. This significantly improved the Lightning’s rate of roll and reduced control forces for the pilot. This production block and the following P-38L model are considered the definitive Lightnings, and Lockheed ramped up production, working with subcontractors across the country to produce hundreds of Lightnings each month.

Noted P-38 pilots

Richard Bong and Thomas McGuire

The American ace of aces and his closest competitor both flew Lightnings as they tallied 40 and 38 victories respectively. Majors Richard I. "Dick" Bong and Thomas J. "Tommy" McGuire of the USAAF competed for the top position. Both men were awarded the Medal of Honor.

McGuire was killed in air combat in January 1945 over the Philippines, after racking up 38 confirmed kills, making him the second-ranking American ace. Bong was rotated back to the United States as America’s ace of aces, after making 40 kills, becoming a test pilot. He was killed on 6 August 1945, the day the atomic bomb was dropped on Japan, when his P-80 Shooting Star jet fighter flamed out on takeoff.

Charles Lindbergh

The famed aviator Charles Lindbergh toured the South Pacific as a civilian contractor for United Aircraft Corporation, comparing and evaluating performance of single- and twin-engined fighters for Vought. He worked to improve range and load limits of the F4U Corsair, flying both routine and combat strafing missions in Corsairs alongside Marine pilots. In Hollandia, he attached himself to the 475th FG flying P-38s so that he could investigate the twin-engine fighter. Though new to the machine, he was instrumental in extending the range of the P-38 through improved throttle settings, or engine-leaning techniques, notably by reducing engine speed to 1,600 rpm, setting the carburetors for auto-lean and flying at 185 mph (298 km/h) indicated airspeed which reduced fuel consumption to 70 gal/h, about 2.6 mpg. This combination of settings had been considered dangerous; it was thought it would upset the fuel mixture and cause an explosion. Everywhere Lindbergh went in the South Pacific, he was accorded the normal preferential treatment of a visiting colonel, though he had resigned his Air Corps Reserve colonel’s commission three years before. While with the 475th, he held training classes and took part in a number of Army Air Corps combat missions. On 28 July 1944, Lindbergh shot down a Mitsubishi Ki-51 "Sonia" flown expertly by the veteran commander of 73rd Independent Flying Chutai, Imperial Japanese Army Captain Saburo Shimada. In an extended, twisting dogfight in which many of the participants ran out of ammunition, Shimada turned his aircraft directly toward Lindbergh who was just approaching the combat area. Lindbergh fired in a defensive reaction brought on by Shimada’s apparent head-on ramming attack. Hit by cannon and machine gun fire, the "Sonia’s" propeller visibly slowed, but Shimada held his course. Lindbergh pulled up at the last moment to avoid collision as the damaged "Sonia" went into a steep dive, hit the ocean and sank. Lindbergh’s wingman, ace Joseph E. "Fishkiller" Miller, Jr., had also scored hits on the "Sonia" after it had begun its fatal dive, but Miller was certain the kill credit was Lindbergh’s. The unofficial kill was not entered in the 475th’s war record. On 12 August 1944 Lindbergh left Hollandia to return to the United States.

Charles MacDonald

The seventh-ranking American ace, Charles H. MacDonald, flew a Lightning against the Japanese, scoring 27 kills in his famous aircraft, the Putt Putt Maru.

Robin Olds

Main article: Robin Olds

Robin Olds was the last P-38 ace in the Eighth Air Force and the last in the ETO. Flying a P-38J, he downed five German fighters on two separate missions over France and Germany. He subsequently transitioned to P-51s to make seven more kills. After World War II, he flew F-4 Phantom IIs in Vietnam, ending his career as brigadier general with 16 kills.

Clay Tice

A P-38 piloted by Clay Tice was the first American aircraft to land in Japan after VJ-Day, when he and his wingman set down on Nitagahara because his wingman was low on fuel.

Antoine de Saint-Exupéry

Noted aviation pioneer and writer Antoine de Saint-Exupéry vanished in a F-5B-1-LO, 42-68223, c/n 2734, of Groupe de Chasse II/33, out of Borgo-Porreta, Bastia, Corsica, a reconnaissance variant of the P-38, while on a flight over the Mediterranean, from Corsica to mainland France, on 31 July 1944. His health, both physical and mental (he was said to be intermittently subject to depression), had been deteriorating and there had been talk of taking him off flight status. There have been suggestions (although no proof to date) that this was a suicide rather than an aircraft failure or combat loss. In 2000, a French scuba diver found the wreckage of a Lightning in the Mediterranean off the coast of Marseille, and it was confirmed in April 2004 as Saint-Exupéry’s F-5B. No evidence of air combat was found. In March 2008, a former Luftwaffe pilot, Horst Rippert from Jagdgruppe 200, claimed to have shot down Saint-Exupéry.

Adrian Warburton

The RAF’s legendary photo-recon "ace", Wing Commander Adrian Warburton DSO DFC, was the pilot of a Lockheed P-38 borrowed from the USAAF that took off on 12 April 1944 to photograph targets in Germany. W/C Warburton failed to arrive at the rendezvous point and was never seen again. In 2003, his remains were recovered in Germany from his wrecked USAAF P-38 Lightning.

Quoting Smithsonian National Air and Space Museum | Boeing P-26A Peashooter :

The Boeing P-26A of the mid-to-late 1930s introduced the concept of the high-performance, all-metal monoplane fighter design, which would become standard during World War II. A radical departure from wood-and-fabric biplanes, the Peashooter nonetheless retained an open cockpit, fixed landing gear, and external wing bracing.

Most P-26As stationed overseas were eventually sold to the Philippines or assigned to the Panama Canal Department Air Force, a branch of the U.S. Army Air Corps. Several went to China and one to Spain. This one was based at Selfridge Field in Michigan and Fairfield Air Depot in Ohio between its acceptance by the U.S. Army Air Corps in 1934 and its transfer to the Canal Zone in 1938. It was given to Guatemala in 1942 and flew in the Guatemalan air force until 1954. Guatemala donated it to the Smithsonian in 1957.

Quoting Smithsonian National Air and Space Museum | Vought F4U-1D Corsair :

By V-J Day, September 2, 1945, Corsair pilots had amassed an 11:1 kill ratio against enemy aircraft. The aircraft’s distinctive inverted gull-wing design allowed ground clearance for the huge, three-bladed Hamilton Standard Hydromatic propeller, which spanned more than 4 meters (13 feet). The Pratt and Whitney R-2800 radial engine and Hydromatic propeller was the largest and one of the most powerful engine-propeller combinations ever flown on a fighter aircraft.

Charles Lindbergh flew bombing missions in a Corsair with Marine Air Group 31 against Japanese strongholds in the Pacific in 1944. This airplane is painted in the colors and markings of the Corsair Sun Setter, a Marine close-support fighter assigned to the USS Essex in July 1944.

Long Description:
No reconnaissance aircraft in history has operated in more hostile airspace or with such complete impunity than the SR-71 Blackbird. It is the fastest aircraft propelled by air-breathing engines. The Blackbird’s performance and operational achievements placed it at the pinnacle of aviation technology developments during the Cold War. The airplane was conceived when tensions with communist Eastern Europe reached levels approaching a full-blown crisis in the mid-1950s. U.S. military commanders desperately needed accurate assessments of Soviet worldwide military deployments, particularly near the Iron Curtain. Lockheed Aircraft Corporation’s subsonic U-2 (see NASM collection) reconnaissance aircraft was an able platform but the U. S. Air Force recognized that this relatively slow aircraft was already vulnerable to Soviet interceptors. They also understood that the rapid development of surface-to-air missile systems could put U-2 pilots at grave risk. The danger proved reality when a U-2 was shot down by a surface to air missile over the Soviet Union in 1960.

Lockheed’s first proposal for a new high speed, high altitude, reconnaissance aircraft, to be capable of avoiding interceptors and missiles, centered on a design propelled by liquid hydrogen. This proved to be impracticable because of considerable fuel consumption. Lockheed then reconfigured the design for conventional fuels. This was feasible and the Central Intelligence Agency (CIA), already flying the Lockheed U-2, issued a production contract for an aircraft designated the A-12. Lockheed’s clandestine ‘Skunk Works’ division (headed by the gifted design engineer Clarence L. "Kelly" Johnson) designed the A-12 to cruise at Mach 3.2 and fly well above 18,288 m (60,000 feet). To meet these challenging requirements, Lockheed engineers overcame many daunting technical challenges. Flying more than three times the speed of sound generates 316° C (600° F) temperatures on external aircraft surfaces, which are enough to melt conventional aluminum airframes. The design team chose to make the jet’s external skin of titanium alloy to which shielded the internal aluminum airframe. Two conventional, but very powerful, afterburning turbine engines propelled this remarkable aircraft. These power plants had to operate across a huge speed envelope in flight, from a takeoff speed of 334 kph (207 mph) to more than 3,540 kph (2,200 mph). To prevent supersonic shock waves from moving inside the engine intake causing flameouts, Johnson’s team had to design a complex air intake and bypass system for the engines.

Skunk Works engineers also optimized the A-12 cross-section design to exhibit a low radar profile. Lockheed hoped to achieve this by carefully shaping the airframe to reflect as little transmitted radar energy (radio waves) as possible, and by application of special paint designed to absorb, rather than reflect, those waves. This treatment became one of the first applications of stealth technology, but it never completely met the design goals.

Test pilot Lou Schalk flew the single-seat A-12 on April 24, 1962, after he became airborne accidentally during high-speed taxi trials. The airplane showed great promise but it needed considerable technical refinement before the CIA could fly the first operational sortie on May 31, 1967 – a surveillance flight over North Vietnam. A-12s, flown by CIA pilots, operated as part of the Air Force’s 1129th Special Activities Squadron under the "Oxcart" program. While Lockheed continued to refine the A-12, the U. S. Air Force ordered an interceptor version of the aircraft designated the YF-12A. The Skunk Works, however, proposed a "specific mission" version configured to conduct post-nuclear strike reconnaissance. This system evolved into the USAF’s familiar SR-71.

Lockheed built fifteen A-12s, including a special two-seat trainer version. Two A-12s were modified to carry a special reconnaissance drone, designated D-21. The modified A-12s were redesignated M-21s. These were designed to take off with the D-21 drone, powered by a Marquart ramjet engine mounted on a pylon between the rudders. The M-21 then hauled the drone aloft and launched it at speeds high enough to ignite the drone’s ramjet motor. Lockheed also built three YF-12As but this type never went into production. Two of the YF-12As crashed during testing. Only one survives and is on display at the USAF Museum in Dayton, Ohio. The aft section of one of the "written off" YF-12As which was later used along with an SR-71A static test airframe to manufacture the sole SR-71C trainer. One SR-71 was lent to NASA and designated YF-12C. Including the SR-71C and two SR-71B pilot trainers, Lockheed constructed thirty-two Blackbirds. The first SR-71 flew on December 22, 1964. Because of extreme operational costs, military strategists decided that the more capable USAF SR-71s should replace the CIA’s A-12s. These were retired in 1968 after only one year of operational missions, mostly over southeast Asia. The Air Force’s 1st Strategic Reconnaissance Squadron (part of the 9th Strategic Reconnaissance Wing) took over the missions, flying the SR-71 beginning in the spring of 1968.

After the Air Force began to operate the SR-71, it acquired the official name Blackbird– for the special black paint that covered the airplane. This paint was formulated to absorb radar signals, to radiate some of the tremendous airframe heat generated by air friction, and to camouflage the aircraft against the dark sky at high altitudes.

Experience gained from the A-12 program convinced the Air Force that flying the SR-71 safely required two crew members, a pilot and a Reconnaissance Systems Officer (RSO). The RSO operated with the wide array of monitoring and defensive systems installed on the airplane. This equipment included a sophisticated Electronic Counter Measures (ECM) system that could jam most acquisition and targeting radar. In addition to an array of advanced, high-resolution cameras, the aircraft could also carry equipment designed to record the strength, frequency, and wavelength of signals emitted by communications and sensor devices such as radar. The SR-71 was designed to fly deep into hostile territory, avoiding interception with its tremendous speed and high altitude. It could operate safely at a maximum speed of Mach 3.3 at an altitude more than sixteen miles, or 25,908 m (85,000 ft), above the earth. The crew had to wear pressure suits similar to those worn by astronauts. These suits were required to protect the crew in the event of sudden cabin pressure loss while at operating altitudes.

To climb and cruise at supersonic speeds, the Blackbird’s Pratt & Whitney J-58 engines were designed to operate continuously in afterburner. While this would appear to dictate high fuel flows, the Blackbird actually achieved its best "gas mileage," in terms of air nautical miles per pound of fuel burned, during the Mach 3+ cruise. A typical Blackbird reconnaissance flight might require several aerial refueling operations from an airborne tanker. Each time the SR-71 refueled, the crew had to descend to the tanker’s altitude, usually about 6,000 m to 9,000 m (20,000 to 30,000 ft), and slow the airplane to subsonic speeds. As velocity decreased, so did frictional heat. This cooling effect caused the aircraft’s skin panels to shrink considerably, and those covering the fuel tanks contracted so much that fuel leaked, forming a distinctive vapor trail as the tanker topped off the Blackbird. As soon as the tanks were filled, the jet’s crew disconnected from the tanker, relit the afterburners, and again climbed to high altitude.

Air Force pilots flew the SR-71 from Kadena AB, Japan, throughout its operational career but other bases hosted Blackbird operations, too. The 9th SRW occasionally deployed from Beale AFB, California, to other locations to carryout operational missions. Cuban missions were flown directly from Beale. The SR-71 did not begin to operate in Europe until 1974, and then only temporarily. In 1982, when the U.S. Air Force based two aircraft at Royal Air Force Base Mildenhall to fly monitoring mission in Eastern Europe.

When the SR-71 became operational, orbiting reconnaissance satellites had already replaced manned aircraft to gather intelligence from sites deep within Soviet territory. Satellites could not cover every geopolitical hotspot so the Blackbird remained a vital tool for global intelligence gathering. On many occasions, pilots and RSOs flying the SR-71 provided information that proved vital in formulating successful U. S. foreign policy. Blackbird crews provided important intelligence about the 1973 Yom Kippur War, the Israeli invasion of Lebanon and its aftermath, and pre- and post-strike imagery of the 1986 raid conducted by American air forces on Libya. In 1987, Kadena-based SR-71 crews flew a number of missions over the Persian Gulf, revealing Iranian Silkworm missile batteries that threatened commercial shipping and American escort vessels.

As the performance of space-based surveillance systems grew, along with the effectiveness of ground-based air defense networks, the Air Force started to lose enthusiasm for the expensive program and the 9th SRW ceased SR-71 operations in January 1990. Despite protests by military leaders, Congress revived the program in 1995. Continued wrangling over operating budgets, however, soon led to final termination. The National Aeronautics and Space Administration retained two SR-71As and the one SR-71B for high-speed research projects and flew these airplanes until 1999.

On March 6, 1990, the service career of one Lockheed SR-71A Blackbird ended with a record-setting flight. This special airplane bore Air Force serial number 64-17972. Lt. Col. Ed Yeilding and his RSO, Lieutenant Colonel Joseph Vida, flew this aircraft from Los Angeles to Washington D.C. in 1 hour, 4 minutes, and 20 seconds, averaging a speed of 3,418 kph (2,124 mph). At the conclusion of the flight, ‘972 landed at Dulles International Airport and taxied into the custody of the Smithsonian’s National Air and Space Museum. At that time, Lt. Col. Vida had logged 1,392.7 hours of flight time in Blackbirds, more than that of any other crewman.

This particular SR-71 was also flown by Tom Alison, a former National Air and Space Museum’s Chief of Collections Management. Flying with Detachment 1 at Kadena Air Force Base, Okinawa, Alison logged more than a dozen ‘972 operational sorties. The aircraft spent twenty-four years in active Air Force service and accrued a total of 2,801.1 hours of flight time.
