Following an engine fire in flight, the crew diverted to Tachikawa AFB for an emergency landing. The aircraft belly landed and came to rest in flames. There were no casualties but the airplane was written off.

The heavy bomber left Kadena AFB at the end of the day on a bombing mission to Korea. Around 2154LT, the last radio contact was recorded while the aircraft was cruising about 100 miles north of its departure point. SAR operations were conducted but eventually suspended as no trace of the aircraft nor the crew was found.

On final approach to Fairchild AFB, the six engine aircraft crashed short of runway and came to rest in flames against a snow bank. All crew members were evacuated safely while the aircraft was destroyed by fire.

En route, an engine caught fire and exploded. All 13 crew members decided to bail out and abandoned the aircraft that dove into the ground and crashed in a mountainous area located 7 km west of Yokosuka. The airplane was destroyed while all 13 crew members were found alive.

On final approach to Frankfurt-Main Airport, the aircraft went out of control and crashed in few houses located in Raunheim, about 6 km west of the airport. While all five crew members were injured, three people on the ground were killed.

The crew was performing a flight from Mountain Home AFB, Idaho, to San Diego. While cruising by night at an altitude of 11,000 feet, one of the engine failed. All six crew members decided to bail out and abandoned the aircraft that crashed on the slope of the Towne Peak (7,287 feet high) located in the Dolomite canyon, in the Death Valley, about seven miles northeast of Panamint Springs. All six occupants were found unarmed while the aircraft was destroyed. It was later reported that the remaining engine was running normally at impact.

En route from Kadena Airbase and while approaching the North Korean coast, the heavy bomber went out of control and crashed into the Yellow Sea few km off Nampo. No trace of the aircraft nor the 14 crew members was found.

An engine failed en route, forcing the crew to ditch the aircraft into the Japan Sea, off the South Korean coast. All occupants were evacuated safely while the airplane sank and was lost.

Shortly after takeoff from Mather AFB, while in initial climb, the crew informed ground about an engine failure and elected to return for an emergency landing. The pilot-in-command completed a 180 turn to reach the approach path when, on final approach, the twin engine aircraft went out of control and crashed in a crowded guard house at Mather Air Force base and exploded, turning the building into a "flaming matchbox." While all three crew members were injured, six people in the building were killed while 61 others were injured. All of them were guard house prisoners. They returned from lunch to the one-room building just in time to be caught in a fiery trap.
Crew:
2nd Lt Peter A. Keck, pilot,
Lt Robert C. Grout, copilot,
