In a similar mould of stupidity is the guy who thought it would be a good idea to hold up an airline flight, rob passengers and crew of all their valuable items and then make his 'cunning' escape. This involved getting the pilot to descend below 10,000ft before jumping out of the aircraft with a parachute... that he had fashioned himself from bed sheets and the like.
Needless to say it didn't work and his body was found in a rather big hole on a swamp!
But at least he got the pilot to descend so he would have been conscious for the last moments of his life!
