Another record-breaking ingenious design from the workshop of Burt Rutan's Scaled Composites

The Kellett XO-60 represented the final stage in the development of the autogiro, but by then the Sikorsky was producing helicopters that better suited the needs of the Army.

This is one of two Horten tailless gliders at the NASM.

This was the first of a series of flying wing designs Jack Northrop created for the Air Force.

In 1945, William H. Bowlus and Ted Nelson formed the Nelson Aircraft Corporation to build a two-seat, motor glider version of the popular Bowlus BA-100 Baby Albatross.

This rotorcraft proved that a personal helicopter was practical. Moreover, it led to the all-time classic Bell 47.

With all these modifications, I did not recognize this aircraft as a DH Chipmunk.

With this aircraft, Leo Loudenslager established many of the standard aerobatic maneuvers.

In 1969, Darryl Greenamyer broke the 30-year-old speed record for piston-engine aircraft held by the German Messerschmitt Me 209 when he reached 777 kilometers (483 miles) per hour in this heavily modified Grumman Bearcat.

The level of workmanship in this aircraft is comparable to that of the hand-built Dash-80 prototype on which it casts its shadow.

Very interesting semi-tailless delta-wing German aircraft.

The attached flight simulator makes this aircraft look like it has two heads!
