(includes these BONUS kits Bell X-16, McCulloch YH-30 and Lockheed YO-3A) In 1972, the U.S. Air Force issued the Advanced transport STOL transport program for a new medium airlifter that capable of operations into battle zones with short, temporary airfields. Two proposals were accepted for construction as the Boeing YC-14 and McDonnell-Douglas YC-15 prototypes. The Boeing design for STOL performance was based on the use of a supercritical wing, developed by NASA that the high-speed airflow from the engines tended to cling to the upper surface of the wing\/flap system and was thus directed downward to provide powered lift. It was the most efficient powered-lift system ever developed. The first flight of the YC-14 demonstrated superior STOL performance and low-speed maneuverability. However, by the time the YC-14 was ready for production, military priorities had changed. The Air Force decided it needed a larger transport that would fly to standard, conventional airfields rather than into battle zones.
