Two X-25 aircraft were procured by the USAF in 1968 to test a method for improving the chances of rescuing crewmen forced to bail out from their aircraft over enemy territory. If the flyer had a means of controlling his descent after parachuting and could select a landing site, his chances of avoiding capture would be greatly increased.

The unpowered Bensen X-25B “Gyroglider” theoretically could be deployed after the flyer’s parachute had opened. Its rotary wings would be brought up to speed during the descent, the parachute would be detached, and the “Gyroglider” would then be flown as an autogiro to a landing point.

The X-25A “Gyrocopter” represented a more advanced concept with a limited “fly-away” capability. Unlike the X-25B, which had no engine, the X-25A had a 90 hp engine. Following tests at Wright-Patterson Air Force Base, Ohio, the X-25A was delivered to the museum in 1969.

This resembles a helicopter built by the Hiller Co. near Palo Alto CA during the 1950's. It was designed to be dropped by parachute to a downed pilot behind enemy lines.
It could be assembled in minimal time so that the pilot could escape.

There is a model on display at the Hiller Aviation Museum at the San Carlos Airpost. See their website at Hiller.Org.
