The C-40A was flying in formation with a C-54 registered 41-37271, so his crew could photograph the dropping of a dummy combat tank from the C-54. After the tank was released, the pilot of the C-40A made a quick turn to the left, striking the C-54 right wingtip. The C-40A entered a spin and crashed near the runway, killing all five crew members. The C-54 continued on for 700 feet, allowing two passengers to bail out. The plane then crashed in a vertical dive, killing three other crewmen.
