...whiz along for under 1? per passenger mile-less than any existing jet. That efficiency, and the fact that it can use runways too short for smaller, four-engine airliners, is the result of the plane's major technological advance: Lockheed will use three 33,000-lb.-thrust turbofan engines (two mounted under the wings and one in the tail) like the ones slated for its huge C-5A military transport...
...Fairchild Miller's development costs will be shaved in half. In addition, the U.S. company will sell the F28 in the Western Hemisphere, purchase such F228 components as the tail assembly, wing segments and a shortened fuselage from the Dutch, and will use Rolls-Royce turbofan engines that have been specifically designed for the F-228. The company, as a result, hopes to keep its cost $1,000,000 below the $3,500,000 to $4,000,000 price tag of competing compact jets...
Swinging Wing. The TFX-now known officially as the F-111-is something of a pioneer aircraft. The two-man, 1,650-m.p.h. plane is equipped with the world's first afterburning turbofan engines, has a revolutionary swing-wing-the sort envisioned in one of the designs for the nation's first commercial supersonic transport. The wing, which is crucial to the multipurpose role planned for the TFX, enables the plane, in effect, to redesign itself in flight. The plane sweeps back its wings in a dartlike configuration for supersonic flight, extends them to full span to slow...
...companies stalled, British Aircraft, which had the One-Eleven on its drawing boards, built in the features that American wanted-with no promise of an order. Just to please Customer Pan Am, Dassault willingly redesigned its Mystère 20* to make it larger and switched to General Electric turbofan jet engines. If such aggressiveness continues and U.S. framemakers offer no better fight, the U.S. could be toppled from the position of planemaker to the world, which it has held ever since the first DC-3 lumbered down the runway...
Giant, Shattered Fish. As soon as it was airborne, the giant and graceful Boeing 707-120B-the latest in jetliners and the pride of American Airlines-rose dramatically, boosted by its new turbofan engines. At about 700 feet the jet banked smoothly to the left in accordance with its flight plan, then veered sharply, almost rolled over completely-and plunged nose first into the tidal marshes of Jamaica...
