U.S. Air Force Staff Sgt. Shaun Kileleman, 44th Fighter Squadron aircrew flight equipment assistant NCO in charge, uses a combined aircrew system tester to check an anti-gravity suit Jan. 18, 2018, at Kadena Air Base, Japan. The anti-gravity suit enables pilots to endure accelerated forces by keeping blood flow from their lower extremities while experiencing large amounts of gravitational force.
