The Grumman Aircraft Corporation constructed two X-29s. NASA evaluated the X-29 at its Flight Research Facility. The X-29 research project examined high angle attack characteristics and advanced technologies. In 1984, NASA conducted X-29’s test flight. From 422 research missions, NASA learned that forward-swept wings and movable canards provided pilots terrific control reactions for a 45 degree angle of attack. The aircraft reached a top altitude of 50,000 feet. The X-29 didn’t meet all projections. It didn’t reduce the aerodynamic drag as expected. The first X-29 prototype is exhibited at the National Museum of the Air Force in Ohio. The second is shown at NASA’s Flight Research Center.
