Sometimes you see a vintage plane that makes you scratch your head. Case in point is the US Air Force’s X-29 of the 1980s that looks like a fighter with the wings stuck on backwards. Was this a daft mistake or a great leap forward? Let’s have a look.
If you visit the National Museum of the Air Force in Dayton, Ohio or NASA’s Armstrong Flight Research Center in Edwards, California, you’re likely to see one to two prototypes of one of the oddest aircraft to leave the drawing board.
The Grumman X-29 may resemble the product of some kid who put together a model airplane without reading the instructions, but there was some serious thinking behind building an aircraft with its wings sweeping dramatically forward instead of back.
X-29
In the 1930s, aeronautical engineers were experimenting with various wing designs, including forward-swept wings. The idea behind this unique wing configuration was to improve aerodynamics, increase maneuverability, and allow for steeper angles of attack.
In the 1970s, new advancements in materials and technology prompted DARPA, the US Air Force, and NASA to revisit the concept of forward-swept wings. This led to the development of the X-29, which first took flight in 1984 and served as a research testbed until 1992.

Despite its remarkable agility, the X-29 was notoriously unstable in flight. To address this, Grumman installed a cutting-edge fly-by-wire system to assist in controlling the aircraft’s flight.
Why More Aircraft Don’t Have Forward Swept Wings
In many ways, the X-29 was a success in providing valuable data for future aircraft designs. However, its forward-swept wing performance did not meet expectations, leading to a shift towards stealth technology in future fighter and bomber designs.
Still, the X-29 left its mark on aviation history and remains a fascinating piece of aeronautical experimentation.
