...geared the first to the front wheels and the second to the back. To soup up the engines to a total of 850 h.p., Thompson and his buddy, Fred Voigt, added a magneto to each for hot-spark firing (standard ignition gradually weakens as engine speed increases), lengthened the piston strokes by five-eighths of an inch, rebored the cylinders and boosted the compression ratio from 8 to 1 to 12 to 1. At the heart of the retooled engines were specially ground camshafts that let the engines wind up to 5,800 r.p.m...
...year, American Airlines President C. R. Smith and Pan American Boss Juan T. Trippe plan to have eleven jets in the air. The trouble is that the U.S. airways are not-and will not be-ready to mix the 550-m.p.h. jets with 350-m.p.h. piston planes in real safety...

Around the world, the fields are loaded with thousands of U.S. planes, from the 22-year-old DC-3s to the Super Constellations and DC-7s. In the jet age, U.S. planemakers also plan to dominate the air. Last week Douglas Aircraft Co. rolled out its 176-passenger DC-8 for its first flight. With an escort of two jet chase planes to observe and take pictures, a veteran Douglas test crew took the DC-8 to 31,000 ft., flew it over the Pacific at 360 m.p.h...
...some DC-7s as a down payment on 30 DC-8s; Lockheed is dickering in the same way to sell its turboprop Electras. All told, U.S. airlines have ordered 257 jets and 172 turboprops. When these come into service, their extra speed and capacity will send about 700 piston aircraft onto the used-plane market...
...moment, none of the planemakers is sure of customers for the piston aircraft, though there are 1,100 DC-3s and DC-4s around the world that will soon have to be replaced. Even without the assurance of a market, the planemakers will take trade-ins because, according to one. "a trade-in may be just enough to tip a deal your...
