" In 1912, a man named Franz Reichelt jumped off the Eiffel Tower wearing a parachute suit he designed himself. He jumped to test his invention--he expected to fly--but instead he fell straight down, hitting the ground like a meteor and leaving a 5.9-inch-deep crater from the impact. Did he mean to kill himself? Doubtful. I think he was just cocky, and also stupid. "
