Intricate components located the bottom of an egress seat, waiting to be installed to a U-2 Dragon Lady, Jan. 14, 2020 at Beale Air Force Base, California. If a pilot ever needs to eject from an aircraft, gas pressure will be sent through these hoses and to the explosives so that a pilot can escape the aircraft.
