Falke had its own power, an autopilot and a computer to control the hydraulically actuated flight control surfaces of the spaceplane.
It landed on a long runway as a spaceplane.
Almost universally, the designs were small, fully reusable, and based around delta wing or lifting body spaceplanes.
The orbiter was a reusable winged spaceplane, a mixture of rockets, spacecraft, and aircraft.
The vast majority of the entries, however, were two-stage spaceplanes.
Rocket-powered aircraft and spaceplanes have also made unpowered landings.
The various proposed crewed spacecraft were mostly spaceplanes.
The costs were expected to be reduced by the reusable nature of the spaceplane and launch facilities and by somewhat lower fuel-consumption than conventional systems.
