JetCopters: Fact or Fiction?

Just an FYI --- I stumbled upon this recently. Lockheed had an experimental craft back in the early1960s that would take off like a helicopter and the rotors would disengage in order for a turbine and wings to take over like an airplane. About 20 years before the birth of Star Frontiers, we had actual jetcopters that really worked. A total of two were made for the US Air Force, the first sported a three-blade rotor that proved instable during turbine mode at higher speeds when tested in late 1962, so the second was outfitted with a four blade rotor. The second version was clocked at just over 300mph in 1965.<br /><br /><img src="http://www.aerofiles.com/lock-xh51a.jpg&quot; />
