Pentecost Hoppicopter

This personal helicopter concept was developed by Horace T. Pentecost during WW2. Consisting of 12 foot diameter contra rotating blades powered by a 15-20 hp engine, the whole machine was to be strapped to a soldier's shoulders. Landing gear was the operators feet. Under ideal circumstances probably ok, but if he stumbled or fell during landing, the results might be spectacular! This prototype actually made about 20 short flights before being retired and is part of the Smithsonian National Air and Space Museum collection.

All I can say is, we're entering the third decade of the 21st Century. Where's my hover car? Happy New Year!
