1. Valerian Abakovsky – The Airplane Train
Before bullet trains and high-speed rails, there was the “Aerowagon” train. The Aerowagon was designed by Russian inventor Valerian Abakovsky, which was equipped with an airplane engine and propeller. He met his end when the train derailed on a test run—on the way back to the capital city of Moscow.
2. Franz Reichelt – The Human Parachute
French inventor Franz Reichelt wanted to devise a solution to a new problem: how people can jump out of planes and not become pancakes. His answer: a parachute suit.
After testing the suit out with dummies, he decided it was safe enough to test the suit out personally. Apparently the dummies were no substitute for the real thing as Reichelt jumped off the lower level of the Eiffel Tower.
As you can guess, he became part of the problem and was killed instantly.
