It had taken off from Angaur Airfield, flying on a bombing mission against anti-aircraft installations on Koror, Palau Islands. Whilst over Koror, the B-24 was hit by anti-aircraft fire . The fuselage fell in a flat spiral until it crashed. 10 crew members were on bored. 9 were killed in the crash except the Navigator, 2nd Lt Wallace F. Kaufman. He was captured by the Japanese and executed.
There was a myth surrounding this footage that it was an American bomb striking the wing of the plane. However, a cleaned up version of the film has been analysed and it shows that the wing is struck from the below. So it was not friendly fire.
