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 maneuverabilit y. 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. In 1979, the Air Force formally cancelled the AMST program for both the YC-14 and the YC-15. As a result, the C-X program, the C-17 evolved.","brand":"Anigrand Craftswork","offers":[{"title":"Default Title","offer_id":53773680116049,"sku":"ANIG2100","price":204.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0865\/4992\/2129\/files\/ANIG2100.jpg?v=1778723806","url":"https:\/\/www.jadlamracingmodels.com\/products\/anigrand-craftswork-anig2100-1-72-boeing-yc-14-advanced-medium-stol-transport","provider":"Jadlam Toys \u0026 Models","version":"1.0","type":"link"}
