B-58 Hustler escape capsule. Each of the three crew members had an ejection seat equipped with this capsule. When activated, it could maintain pressure and oxygen in the capsule in the event of aircraft systems failures, and the pilot's capsule had controls with which he could continue to fly the aircraft.

On ejection, the capsules provided protection against the airblast associated with ejection at supersonic speeds (up to Mach 2) and would float in water landings, acting as a life raft.
