LAUGHLIN AIR FORCE BASE, Texas – Staff Sgt. Keith Lewis, chamber flight lecturer, tells student pilots what altitude they are at, different things occurring at that altitude such as gas expansion, and physiologically what this means for the aircrew member. Senior Airman Brian Evans, chamber operator, physically “drives” the chamber profile, ascending and descending as necessary. (U.S. Air Force photo by Staff Sgt. Austin M. May)
