Visit Visit our website Consider becoming a channel member This World War II era film was produced by the Signal Corps for the U.S. Army Air Forces and scored by the U.S. Army Band. This particular training film discusses human factors involved in high altitude flying. The film takes the viewer through various possible scenarios, shows training and testing techniques using pressure chambers, and looks at typical mistakes and the repercussions thereof. The Air Force Laboratory at Wright Field, Ohio investigated many aspects of manned flight in this era, and likely contributed to this film.
