April 20, 1961 -
Harold Graham made the first untethered flight in a rocket belt near
Niagara Falls, New York.
Harold Graham reached an height of approximately
4 feet (1.2 meters), and then flew smoothly forward at a speed of approximately
10 km/h for a distance of
108 feet (less than
35 meters) and then landed. The flight lasted
13 seconds.
