The Hyper III was designed to help in the M2 lifting body program, it had a flat bottom and sides, and a simple straight wing with no control surfaces[1] that was designed to simulate a pop-out wing that had been proposed for a re-entry vehicle. The Hyper III had twin fins and rudders canted at 40° from the vertical, and hinged elevons on the horizontal surface.[1] The landing gear was a fixed tricycle type, using spring steel legs from a Cessna aircraft.[1] It was fitted with an emergency parachute system and controlled by 5-channel radio link; instrument data was downlinked using a 12-channel radio.[1]
On 12 December 1969 the Hyper III was launched from a helicopter at 10,000 feet. It glided 5 km, turned round, came back and landed. After the three-minute flight it was not flown again as the Center cancelled the program.[1]
