this was never funded. ISINGLASS was intended to overfly the USSR. No images of the vehicle configuration have been released. The Lunar Landing Research Vehicle was a mixed powered vehicle- a jet engine cancelled 5/6 of the force due to gravity, and the rocket power was able to simulate the Apollo lunar lander. Various versions of the Reaction Motors XLR11 rocket engine powered the X-1 and X-15, but also the Martin Marietta X-24A, Martin Marietta X-24B, Northrop HL-10, Northrop M2-F2, Northrop M2-F3, and the Republic XF-91 Thunderceptor, either as a primary or auxiliary engine. The Northrop HL-10, Northrop M2-F2 and Northrop M2-F3 were examples of a lifting body, which are aircraft which have very little if any wing and simply obtain lift from the body of the vehicle. Another example is backslider rockets in amateur rocketry. Post Cold War era The EZ-Rocket research and test airplane was first flown in 2001. After evaluating the EZ-Rocket, the Rocket Racing League developed three separate rocket racer aircraft over the following decade. During 2003, another privately developed rocket-powered aircraft performed its first flight. SpaceShipOne functions both as a rocket-powered aircraft—with wings and aerodynamic control surfaces—as well as a spaceplane—with RCS thrusters for control in the vacuum of space. For their work, the SpaceShipOne team were awarded the Space Achievement Award. In April 2019, the Chinese company Space Transportation carried out a test of a 3,700-kilogram technology demonstrator named Jiageng-1. The 8.7-meter-long plane has a wingspan of 2.5 meters and it is a part of development of the larger, future Tianxing-I-1 vertical takeoff, horizontal landing reusable launch vehicle.
