23 July 1944 – “Two Curtiss RA-25A Shrikes, of the 4134th Base Unit, Spokane Army Air Field, collide in flight while participating in a flypast for an air show near Spokane, Washington.
Part of a three-plane formation, the left-hand aircraft collided with the middle plane during a turn, both crashing into a valley. Pilot 2nd Lt. George E. Chrep and engineer-rated passenger Sgt. Joseph M. Revinskas were killed in the crash of 42-79804, while pilot 2nd Lt. William R. Scott and passenger Captain Ford K. Sayre, a noted snow skier on the east coast, were killed in the crash of 42-79826.
A Paramount Pictures newsreel crew caught the accident on film, which was examined by the crash investigation board for clues to the accident. This footage was later incorporated into the 1956 film Earth vs. the Flying Saucers.”
