In May 1943, the crew of the Memphis Belle completed their 25th and final mission. With them on this mission was filmmaker William Wyler. Wyler and his film crew had been documenting this experiences of the B-17 crews in the air war over Europe. Their footage, which gives an unflinching, up close look at the aerial combat that these men saw in WWII, was used for a documentary film that was released to the public in 1944.
