Nose-down went the P-39, trailing a white exhaust plume. Her prop, turning just fast enough to keep her Allison engine warm, began to windmill. The airspeed indicator hand began to turn-350 -400. But Andy McDonough kept his eye fixed mostly on the hands of the sensitive altimeter. Around 5,000 he eased the ship out into level flight, called the field again: "Dive completed . . . returning to base." When he landed, a doctor checked him over. Nothing wrong. Mechanics checked the Airacobra for skin wrinkles, other evidences of strain. All O.K. Andy McDonough was on his way back...
...world's most formidable, is no longer satisfied with its liquid-cooled Rolls-Royce Merlin engine. U. S. airmen found the report disturbing because the Army Air Corps has gone in up to its ears for a similar engine of similar horsepower -the 1,090-h.p., liquid-cooled Allison...
Fortnight ago, for reasons that no one seemed able to make plain to laymen, the Army laid out another $69,000,000 contract for Allison engines. The Army thus raised its bet on an apparently underpowered engine (and planes designed for it) to $159,500,000. And the Army also had $62.448,000 out in orders for Rolls-Royce Merlins (to be built by Packard...
Meantime the U. S. Navy felt no such pains in the head. It has bought an Allison-powered plane or two to keep up with the development parade but has stuck to the air-cooled engine for its fighter designs. Result of the Navy's unwillingness to abandon one design for another is that its newest fighter, the Vought-Sikorsky F4U (TIME, Dec. 9), is the fastest airplane built in the U. S.; its 2,000-h.p. air-cooled engine has power to burn...
...Allison and Merlin should prove to be out-of-date, the Air Corps will have a lot of explaining, a lot of design switching to do. One possibility is that liquid-cooled engine manufacturers may have to switch over to manufacture of the new Rolls-Royce, with all the headaches that retooling and new airplane design would bring with it. Another is that Allison, whose production is now only 350 engines a month (with a schedule of 1,000 by next Nov. 1), may perfect the 2,000-h.p.-plus 24-cylinder engine now in its research division...
