It's always good to have the courage of your convictions, but sometimes it can all go a bit pear shaped.
This is Franz Reichelt, a man who invented a new form of parachute that could be worn as a jacket. To demonstrate how it would work, in 1912 he jumped off the Eiffel Tower in Paris.
Sadly for him, the parachute/jacket combination must have come from the same Acme Corporation store that Wile E. Coyote in the Road Runner cartoons uses, and he plummeted to his death.
He might have been barmy to leap off the tower in the first place, but that still took a hell of a lot of courage.
The video of the jump is below, and you will see him hesitating before jumping, with, as it turned out, good reason.
