Testing an aircraft
Back in the 1940s, when aircraft were not created, people used to cycle. The men in this picture had their first picture taken in an aircraft just before it took off. It was a demonstration of how the aircraft worked.
William Becker, who was the Mayor of St. Louis, was also on the aircraft. Once the craft took off, the right-wing broke off, making the plane crash and killing all on board. The demonstration failed to work.
