Special Weapons Emergency Separation System (SWESS), also known informally as the dead man's switch, was a nuclear bomb release system that the United States Air Force Strategic Air Command built into bombers such as the B-52 Stratofortress. The system's purpose was to ensure that an aircraft's payload of nuclear weapons would detonate in the event of the crew becoming debilitated by enemy defences such as missiles.[1] Once armed, the system would ensure that the onboard nuclear weapons detonated if the aircraft dropped below a predetermined altitude.
