Meanwhile, Boeing is going ahead as best it can. The B-2707 still has some design problems; foremost among them is the sonic booms it will create whizzing along at Mach 2.7 and the airport noise its engines will cause. But Boeing is confident that its swing wing, which folds back along the fuselage at 1,800 m.p.h. and opens out at slower subsonic speeds, may solve much of the boom and vvrrooom. And even while some engineers work at refinements such as these, others are already seriously at work on a new generation of jets to eventually follow. They...
Last year Argentina bought 25 subsonic Douglas A-4B fighters from the U.S. Chile promptly dashed out for more planes and was soon negotiating for the Hawker Hunters. Not to be outdone, Peru last week was discussing purchase of 16 Mach-2.1 English Electric Lightnings and a flock of advanced-model Hawker Hunters. Meantime, Venezuela was suddenly losing its love for its F-86 Sabre jets, which it bought from the U.S. five years ago. So it, too, was dickering-with Sweden for 20 Saab
Draken fighters, a Mach-2.2 all-weather interceptor...
...President Fernando Balaunde Terry, "we will buy them from any other country willing to sell to us." And possibly cheaper, since Europe is hungry for the business. The Swedes are offering the Saab Draken fighter for some $700,000, compared with $900,000 for Northrop's slower (Mach-1.3) F-5 Freedom Fighter (see U.S. BUSINESS). Brazil claims that five-year terms are the best it can get in the U.S.; the British are offering ten years. As a result, the Brazilians ordered ten Avro-748s from Britain last month, and took an option for more...
...safety-boosting innovations. The hinged nose dips 15° during takeoffs and landings so that pilots can see better. So-called "double-delta" wings-thinly tapered in front and broader at the rear-prevent stalling at low speeds, give extra stability in the treacherous turbulence of travel at Mach...
