AVCO's proposal for the Air Force initial manned space project was a 690 kg, 2.1 m diameter sphere launched by a Titan. It was equipped with a unique stainless-steel-cloth parachute instead of the usual reaction control system and retrorockets. The chute's diameter could be controlled by compressed air bellows. This would orient the vehicle in orbit, provide deceleration for re-entry, and control drag during re-entry. The spacecraft would be boosted by the Titan booster into a 190 km orbit for a one week mission. Despite the aerodynamic control system spacecraft control was automatic and no pilot inputs were required. Maximum G-forces during re-entry were 9 g's and the radiative heat shield was of molybdenum or Inconel. In case of booster failure during ascent to orbit the upper stage would catapult the capsule 1 km from the launch vehicle, followed by a parachute descent to earth. The spacecraft had a ballistic coefficient (W/CdA) of 7.3 kg per square meter. Landing precision was 'within Kansas' (650 x 300 km landing footprint). It was expected that a first manned orbital flight could be achieved 30 months after a go-ahead at a cost of $ 40 million.
