Mmm mmm mmm mmm.
From the wiki:
Franz Reichelt (1879–1912), a tailor, fell to his death off the first deck of the Eiffel Tower while testing his invention, the coat parachute. It was his first attempt with the parachute, and he had told the authorities he would first test it with a dummy.[7]
Would it be mean of me if I said he did test it on a dummy?
