At approximately 4:00 p.m. on Thursday, December 12, 1957, U.S. Air Force B-52D Stratofortress, No. 56-0597, from the 92nd Bombardment Wing, was taking off from Runway 5 at Fairchild Air Force Base (AFB) on a routine training mission. According to eyewitnesses, as the aircraft left the runway, it made an abnormally steep climb to an altitude of approximately 2,000 feet. Fire started coming from the jet engines and pieces of metal began flying off the engine cowlings and mounts. The aircraft stalled, executed an abrupt, right wingover and appeared to level off. But, at an altitude of approximately 500 feet, the plane nose dived and crashed in a stubbled wheat field one mile west of the base. Exploding jet fuel sent a large column of smoke into the sky, attracting scores of curious onlookers. A crew member was injured while eight other occupants were killed: Crew: Maj Ralph Romaine Alworth, † Cpt Douglas Earl Gray, † 1st Lt James Dennis Mann, † Col Clarence Arthur Neely, † Cpt Thomas N. Peebles, † Cpt Douglas Franklin Schwartz, † Cpt Herbert Henry Spiller Jr., † 1st Lt Jack Joseph Vainisi, † T/Sgt Gene I. Graye. Source: http://www.historylink.org/File/9857
Probable cause (official findings): It is believed the loss of control was the consequence of an incorrect wiring of stabilizer trim switch.
