For example, the Space Shuttle Solid Rocket Boosters are equipped with explosive charges so that the boosters can be destroyed in the event that control is lost on launch and a populated area is in danger. This feature can be seen in videos of the Challenger disaster. After the initial disintegration of the shuttle, the two solid rocket boosters continued firing until they exploded simultaneously 37 seconds later. This occurred when the Range Safety Officer decided that the separated boosters had the potential to endanger those on the ground and activated the self-destruct system.[3]
