Self-destruct

A self-destruct is a mechanism which causes a device to destroy itself under a predefined set of circumstances. Self-destruct mechanisms are sometimes found in high security data storage devices, where it is important for the data to be annihilated in emergencies.

Self-destruct mechanisms are also found on devices and systems, the malfunction of which could endanger large numbers of people. The Space Shuttle Solid Rocket Booster rockets, for example, are wired with explosives so that the boosters can be destroyed in the event that it loses control on launch and heads towards a populated area. This feature can be seen in videos of the Challenger explosion. After the initial disintegration of the shuttle, the two solid rocket pods continue flying out of control until they explode simultaneously several seconds later. This occurred when the Range Safety Officer decided that the separated engines had the potential to endanger those on the ground and detonated the self-destruct system.
