Extended description
"Called 'full pressure suits', these special garments provide the wearer with a self-contained capsule of oxygen and atmospheric pressure. The suit is connected to aircraft systems that provide the required pressurization and oxygen. Cockpit cooling is also handled by systems on board the aircraft.

These highly specialized flight suits were maintained by USAF Physiological Support personnel. The Life Support Equipment Branch of the National Aeronautics and Space Administration (NASA) maintained the life support systems on the aircraft."
