On December 13, 1985, the Grumman X-29 became the first supersonic forward swept wing (FSW) aircraft.

There were two built using F-5 airframes. The test program continued for almost ten years.

The Grumman X-29 design exhibited decreased turbulence over conventional jet fighter designs and generally excellent maneuverability.

The forward swept wing configuration of the experimental aircraft made it inherently unstable. It relied on computerized flight controls for constant flight corrections.

The flight control system was made up of six redundant computers. It was estimated that a total systems failure was as likely as a mechanical failure in other aircraft.

The Grumman X-29 is currently on display at the National Museum of the U. S. Air Force located at Wright Patterson Air Force Base near Dayton, Ohio.
