The 1962 jetcopter that floats, flies and drives

 


Compressed air powers this Monte-Copter Triphibian helicopter. A gas-turbine compressor pushes air up through the rotor head and jets it out the rotor tips. Forward propulsion is provided by residual thrust. Entire thrust may be used for taxiing on roadways or water without the rotors turning. Wings with tip tanks serve as outrigger floats. The fiber-glass-hulled craft does 95 m.p.h., cost $30,000.
