	Air Wing #2
		The DC-9 was designed specifically to operate from short runways and on short- to medium-range routes so that the speed, comfort and reliability of jet transportation could be extended to hundreds of communities previously served only by propeller-driven airliners.
		To find a replacement, the Air Force held the Advanced Medium STOL Transport (AMST) competition, with Boeing proposing the Boeing YC-14, and McDonnell Douglas proposing the YC-15.
		However, the AMST competition was ultimately cancelled before a winner had been selected.

	Advanced Medium STOL Transport (AMST) YC-14 and YC-15
		As a result, the C-X (Cargo Transport Aircraft-Experimental) — the future C-17 — evolved from discussions between Office of the Secretary of Defense (OSD) and Air Staff officials on expanding the role of the AMST to include strategic capabilities.
		The demise of the AMST in late 1979 did not surprise the Air Force.
		The AMST, like the C—130, operated as an intratheater aircraft, but a new transport capable of both tactical and strategic airlift would be more cost-effective.

	AMST Prototypes: Boeing YC-14 and McDonnell Douglas YC-15
		The Boeing Model 953 design for STOL performance was based on the use of a supercritical wing, developed by NASA from the wind-tunnel research of Dr. Richard Whitcomb, which provides highly efficient performance from the wing at high subsonic speeds.
		Employing "under-surface blowing" to achieve STOL capability, part of the exhaust was directed downward by the flaps while the rest passed through and then downward over the flaps by means of the "Coanda Effect".
		Both the YC-14 and the YC-15 satisfied the AMST performance requirements, which would later be incorporated into the design of the larger C-17 Globemaster III transport.

		However, the C-17 experience revealed what studies conducted during the AMST had proven and Kadish had pointed out_"the technology was not as well defined as some would lead us to believe." Although McDonnell Douglas did not develop new technologies for the C-17, the way in which the technologies were used was new.
		Also, using STOL capability on a plane expected to fly 2,400 nautical miles (NM) with a 172,200-pound payload to include outsized cargo was much different than using STOL on a plane expected to fly a 400-mile radius with a 27,000-pound payload.

	YC-15 Advanced Medium STOL Transport (AMST)
		Employing "under-surface blowing" to achieve STOL capability, the YC-15's wings were configured with sets of double-slotted flaps which could be extended downward directly into the jet flow from its four turbofan engines.
		The YC-15 was the first military transport to use supercritical wings, a major innovative technology conceived and developed through wind-tunnel research by Richard Whitcomb at NASA Langley.
		The McDonnell Douglas YC-15 Advanced Medium STOL (Short-Takeoff and Landing) Transport aircraft landed at Edwards at the end of its maiden flight on 26 August 1975, and was joined by the second prototype in December of that year.

		Using advanced aerodynamics and an innovative NASA powered-lift concept, the C-17 combines the load carrying capacity of the C-5 with the short takeoff and landing performance of the C-130.
		Several major components of the C-17 are made of advanced composites (ailerons, rudders, elevators, vertical and horizontal stabilizers, flap hinge fairings, main landing gear pod panels, and winglets).
		In the early 1960’s, a British BAC 111 T-tail transport experienced a fatal accident in which the aircraft entered a deep stall and descended in an uncontrollable condition at a very high rate of descent with an almost horizontal fuselage attitude until impact.

	Cargo Aircraft Designations
		At the end of the war, USAAF decided to standardize on the Douglas C-54 as its four-engined transport of choice, and most of the C-69s were promptly declared surplus and sold on the commercial market.
		Small airline cabin and doors prevented use as heavy cargo and troop transport, so they were used primarily for crew ferrying and later for training.
		C-22B was designation given to four ex-airline Boeing 727-100 three-jet transports used by Air National Guard to carry inspection and training teams from Washington to various points in the USA.

	MILITARY PARADE MAY-JUNE
		It is scheduled for adoption by the air forces of Russia, Ukraine and other CIS countries to materially enhance their transport capabilities and replace the now almost obsolete An-12 aircraft which is about to exhaust its service life, and to perform more effectively certain missions currently performed by the IL-76 and An-22 aircraft.
		The first Soviet-made STOL aircraft was the An-72 transport capable of taking off from a 600-m long strip and carrying 5 t of cargo to a distance of 700 km.
		In the early 1970s, the USA embarked on an AMST (advanced medium STOL transport) program which provided for the creation of an aircraft capable of performing takeoff from and landing on unpaved strips up to 3,000 ft (915 m) long.

		Too bad the US never took production of the AMST (Advanced Medium STOL Transport) concepts: the Boeing YC-14 was probably the template for the Russian An-72 "Coaler" transport, using 2 upper-wing turbofans to provide USB (Upper Surface Blowing) to increase lift performance.
		Both aircraft were built to a specification of lifting 27,000lbs in STOL from a 2000ft rough strip, or 62,000lbs in normal take-off.
		The AMST was drafted up in 1972 as a replacement for the Hercules, and the two aircraft started trials in 1975 (YC-15), and 1976 (YC-14).

		When Transcontinental and Western Air Inc. (TWA) asked Douglas to design a commercial transport to replace its aging fleet of Ford and Fokker trimotors and to compete head-on with United Air Lines' new Boeing Model 247 airliner, Douglas designed an all-metal, twin-engine transport that exceeded all requirements.
		It was the first airliner to make money for its operators by transporting people, independent of mail contracts.
		Today 2,727 Douglas and McDonnell Douglas commercial transports fly with 320 operators around the globe, ensuring the legacy will continue well into the 21st century.

		Air transport is the preferred method for moving the reserve because it is fast and not dependent on open ground routes as are motorized or mechanized modes of transport.
		Brigades assigned strike campaign missions either are relieved from area responsibility in advance of the mission or, preferably, are constituted as specialized forces held at the national or regional levels.
		The most important one is that hogogenizing the Army into physically impotent medium weight armored car motorized units just because they have computers sub-optimizes them in our complex world where light, medium and heavy type units have necessary physical firepower, mobility and protection advantages that cannot be replicated by mouse-clicks.
