Not many people know that working rocket belts actually exist. They were developed for the Army in the late 1950s, and after the Army decided they were not suitable for military use, dedicated civilians kept a few models in operation.

Today, three rocket belts are known to exist. Two are owned by Howard “Kinnie” Gibson, a daredevil and stuntman who acquired the patent on an essential part of the design.

The third belt — whose builders claim it is the most advanced ever constructed — has gone missing, leaving a trail of death and intrigue in its wake. More here.
