The Rotodyne was designed to be a new form of mass transport in the 1950s and 60s .
It's not a helicopter, but a rotodyne has an unpowered, freely spinning rotor that lifts more than half the aircraft's weight.
With this design, it flew faster than any helicopter of the era, and it was far more efficient than any other aircraft.
But then, as it looked set to revolutionize intercity transport, it just disappeared.
In April , the new helicopter service is due to open from the top of the Pan Am building in New York .
The Rhododyne failed to change air travel in the 1960s .
Ferry Aviation spent years developing noise suppressor technology for its tip jets.
Only a single prototype was ever built.
The half helicopter, half plane, once promising to revolutionize intercity travel, disappeared in 1962 .
