I just finished watching the MST3K classic “The Starfighters” about leathery-faced F-104 pilots. Starring Bob Dornan!
Anyways, in one scene just before take-off, the pilots did this weird move. They tilted their head back, held it and jerked it forward, kind of like a massive sneeze. Is this a common thing to do before you take off in a fighter? What does it do?
