Bell Aero Systems Rocket Belt
Bell Aerosystems Rocket Belts. These strap-on devices had a pair of vectorable nozzles controlled by handlebars and enabled the wearer to be thrust over 15-m (50-ft). The only practical application of the Rocket Belt has been as a gimmick in a James Bond movie. Developed versions of the device have been used by NASA astronauts for space-walking.
Neat and potentially useful, the rocket belt has proved difficult to control with the finesse necessary for everyday use by non-experts.
