The famous account of the JATO Rocket Car was one of the original Darwin Awards winners: a man who supposedly met his death in a spectacular manner after mounting a rocket engine on a common automobile. It was originally circulated as a forwarded email.

The story, however, has now been debunked, and is classified as an urban legend.
