Davis-Monthan AFB

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.

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.
