An unpowered reusable flying wing glider employed in conjunction with an aerodynamically shaped spacecraft without wings so as to permit existing airfield launch and ascent to orbit for a rocket engine takeoff thrust to vehicle weight ratio of less than 1. After an optimum climb angle is established and before wing weight and wing drag degrade performance, the wing is released for a glide return to the launch site. The flying wing zero stage would contain tank(s) for fuel or fuel and oxidizer so that at wing release, the spacecraft tanks are full or nearly full for the continuing trajectory to orbit.

A system and process contributing to improving the efficiency and cost reduction of the delivery of payloads to orbit by making possible airfield runway takeoff of the delivery spacecraft, the system and process comprising: (a) a wing without boast propulsion, attached to the upper surface of the delivery vehicle and sized for takeoff and climbout of the combined system; (b) the wing released intact after takeoff at a point in the climbout when the spacecraft has the necessary aerodynamic lift and acceleration to continue to orbit, (c) the wing having the shaping, appendages and controls to support stable controlled flight of the combined spacecraft-wing system; (d) the wing having additional shaping, appendages, together with automatic control and communications required for safe separation from the spacecraft, and gliding, unmanned controlled flight back to the takeoff airfield.
