Jan. 17, 1956: From the annals of improbable aircraft, the Army’s aerocycle, tested at Camp Kilmer, N.J., by Chris Kopp of de Lackner Helicopter. Like a wacky harbinger of Segway technology, the aerocycle was reported to have “two advantages over the conventional helicopter — it is more stable and it is easier to control because the operator steers it by leaning his body in the desired direction.” For the overdetermined navigator who feared leaning too far and falling on the rotating blades, there was a safety belt, and a rubber doughnut absorbed the shock if the pilot came down too hard.

The propeller Segway. This is amazing.
