The AD-1 aircraft with its wing swept. Visible are the twin jet engines that powered the aircraft and the fixed landing gear. The aircraft was 38.8 feet long and 6.75 feet high with a wing span of 32.3 feet, unswept. It was constructed of plastic reinforced with fiberglass and weighed 1,450 pounds, empty. The vehicle was powered by two small turbojet engines, each producing 220 pounds of thrust at sea level. Due to safety concerns, the aircraft was limited to speeds of 170 mph.› AD-1 Project DescriptionMarch 31, 1981NASA Photo /
