Funded by the American military, Harold Graham first flew the rocket belt that was invented by Wendell Moore in 1961. He flew 108 feet (33 meters) in 13 seconds using a pressurized release of hydrogen peroxide. Because of the limited amount of fuel a person can carry, rocket belts only allow for less than a minute of flight and are difficult to control. The design did go on to be modified by NASA for the Manned Maneuvering Unit astronauts use to move independently outside of a space shuttle.
