The A-29C will be used both for training as part of the Test Pilot School’s curriculum and experimental testing of mission ...

It looked like an F-15—but with canards, AI, and STOL tech, this wasn’t just another fighter jet. Known as the most modified ...

Russia's co-orbital satellite tactics are redefining space deterrence and signaling a more aggressive phase in orbital ...

NASA and Boeing have effectively cancelled the X-66 Transonic Truss-Braced Wing (TTBW) concept demonstrator aircraft. Officially described as a "pause," development of the thin-wing airplane is ...

Boeing and NASA will pause work on a new, experimental aircraft design meant to deliver more sustainable options for the future of aviation. The aircraft project — called the X-66A Sustainable ...

Boeing and NASA will pause work on the X-66 Sustainable Flight Demonstrator, an experimental plane design featuring long, thin wings meant to make the plane more fuel efficient.

NASA and Boom Supersonic released an incredible photo capturing the shock waves of the supersonic XB-1 aircraft while it traveled in front of the sun during a Feb. 10 test flight.

NASA tested a model of its X-66 plane inside a wind tunnel at the space agency's Langley Research Center. It could be the future of commercial flight.

In the 1990s, NASA looked into developing a space plane prototype called X-33, but it scrapped the mission in 2001 citing technical issues. Seattle-based Radian Aerospace is now trying to finish ...

It's unclear by how much, but for some idea, NASA hoped that its X-33 space plane would reduce the cost of sending a pound of payload into orbit from $10,000 to $1,000.

NASA and Boeing have provided a glimpse of what the X-66 aircraft will look like. The X-66 is an experimental aircraft designed to help the United States achieve net-zero aviation emissions by 2050.
