The Bristol Spaceplanes Spacebus was a Two Stage To Orbit (TSTO) Manned Spaceplane, with an airbreathing supersonic / hypersonic, delta winged first stage and a second stage powered by a liquid fuelled rocket engine. It was proposed by David Ashford of Bristol Spaceplanes Ltd. in the 1980`s / 1990's. The 6-crew Concorde-sized Spacecab would serve as a prototype for the larger 50-person Spacebus.
