The Space Tourist was a concept of Discraft Corporation of Portland, Oregon, developed by a team led by John Bloomer. The flying saucer would takeoff and land horizontally from conventional runways. John Bloomer was an aerospace engineer with more than 60 patents on disc-platform aircraft. Bloomer's Ship utilized "Blastwave" Pulsejets. The X Prize design was a 30-m diameter, suborbital, hypersonic wave rider aerospace craft using all-flight-regime laminar flow through use of suction over the entire upper surface of the vehicle; massless 'jet-flap' controls achieved by blowing suction air through exhausts; and all flight regime, natural positive stability. Take-off would be at 100 kph with a 50 m ground roll, followed by climb with gradual air-breathing acceleration at fixed angles according to a fixed program, leading to exit of the atmosphere at Mach 10, followed by an unpowered ballistic arc to 120 km altitude. Return to earth was a simple reverse sequence of the take-off profile. The spacecraft would spend five minutes in weightlessness above 30 km altitude, covering 775 km distance in the process.
