the M247  AA gun managed to get itself cancelled after two disasters, firstly while demonstrating its ability to cope with helicopters, managed to destroy a tin outhouse on the range, and second on a rollout in front of the Army general staff its radar controlled automated turret turned and instead of tracking the target put up, instead turned and attempted to hose the review stand with automatic fire, this was only prevented from being the top item on the news by the fact that it hadn't been loaded with ammunition.

Any idiot can face a crisis - it's day to day living that wears you out.
