Boeing B-50 Superfortress

The crew was performing a local training mission at RAF Mildenhall. After an engine failed and caught fire in flight, the captain Robert C. Reagle decided to return to Mildenhall for an emergency landing when the left wing dropped on touchdown. The underwing tank burst into flames when striking the ground and the aircraft went off runway before coming to rest in flames. All crew members were uninjured while the aircraft was partially destroyed by fire.

One hour after departure from Goose Bay bound for Davis-Monthan AFB, the carburetor of the engine number 2 suffered icing and the engine failed. The captain decided to return to Goose Bay for a safe landing when the same engine caught fire shortly later. As the crew was trying to extinguish the fire, the engine number four caught fire as well. In such conditions, the captain ordered his crew to abandon the aircraft. After all 16 crew members bailed out, the aircraft continued a while to the east and eventually crashed in a wooded area located about 94 miles east of Goose Bay. The aircraft disintegrated on impact and all 16 occupants were later rescued and evacuated.

The crew was performing a local training flight in the vicinity of the Davis-Monthan AFB when one (or more?) engine failed. The crew decided to make an emergency landing in a desert area located two miles southeast of the airbase. The aircraft belly landed and slid for several yards before coming to rest. There were no injuries but the aircraft christened 'Lucky Lady II' was damaged beyond repair. It completed the first nonstop world tour from February 26 till March 6, 1949.

The crew was performing a navigational exercice out from Biggs AFB, Texas. While cruising at an altitude of 7,000 feet, the aircraft went into a spin and crashed in a vertical attitude in a huge explosion in a field located southwest of Lebanon. All 16 crew members, among them four officers, were killed. The impact and the blast tore a hole in the ground that was about 18 feet deep and at least 75 feet wide.

The crew was engaged in a navigational exercice from Davis-Monthan AFB. About 19 minutes after takeoff, while cruising at the assigned altitude of 12,700 feet, a propeller blade failed on the engine number three. The engine vibrated and detached from its mount. It then struck the right wing and the fuselage, causing a fire. Out of control, the aircraft dove into the ground and six of the ten crew members were able to bail out before the aircraft crashed in a desert area located about 44 miles northeast of Davis-Monthan AFB.

On approach to McDill AFB, the aircraft caught fire. Five crew members were able to bail out before the aircraft crashed into the Tampa Bay. Seven other crew members were killed.

The heavy bomber departed Davis-Monthan AFB in Tucson at 0615LT for a routine training mission that involved navigation, aerial refueling and camera gunnery training. After transferring 870 gallons of fuel to a KB-29 over Yuma, the crew pressurized the cabin and began to climb to 20,000 feet. While climbing through 17,000 feet, at about 0815LT, the master fire warning light suddenly illuminated on the pilot's instrument panel as the right scanner simultaneously reported a fire streaming from Number 3 engine. There were three successive minor explosions that rolled the bomber onto a 45 degree angle right bank. With the right wing engulfed in flames, the ship then fell into a steep right turn and began to disintegrate. As the bomber broke apart in the sky, only two men of the crew of fourteen were able to escape, the copilot Lt William Gentry and the bombardier, Captain John Lee. The wreckage was spread over a two-mile area of remote desert terrain.

The aircraft departed RAF Lakenheath at 0925LT on a training mission consisting of a climb to 25,000 feet, break up the formation then drop 16,500 pounds of high explosive bombs individually on the bombing target at Heligoland. During the initial climb, while at a height of 500 feet, the captain reported to ATC that all was OK on board. Shortly later, while climbing into clouds, the aircraft went out of control, dove into the ground and crashed in a huge explosion in a field located half a mile southeast of Isleham. The aircraft was totally destroyed by impact forces and several explosions caused by the bombs and the 6,000 gallons of fuel. All 12 crew members were killed.
