MAJ. JAMES DOOLITTLE’S speed record for land planes fell when James R. Wedell of Louisiana streaked across the Chicago skies in his Wedell-Williams 44 monoplane at an average of 305.33 m.p.h. topping Major Doolittle’s record of a year ago by more than 10 m.p.h. The plane, which was powered with an 800 hp. supercharged Wasp engine was equipped with a controllable pitch propeller (Hamilton Standard), a feature now becoming common in major racing planes.

Douglas Airliner for Transcontinental Service

EXCEPT for a few amphibions of the “Dolphin” class delivered for private use or for limited transport services, the output of the Douglas plant at Santa Monica, Cal., has to date been definitely militaristic. To meet Transcontinental & Western Air’s requirements for new equipment, however, Douglas has entered the commercial field on a large scale.

Competition for Carburetors

IT IS just a little more than three years since the first public demonstration of a gasoline aircraft engine with electric ignition and with direct injection of the fuel into the cylinder was given at Hartford. Over that length of time the study of the problems of direct injection has gone steadily and quietly forward in several factories and in widely separated government laboratories—to say nothing of the work done in various European countries.

Side Slips

WE SEE by the papers that somebody in Italy has broken the record for upside down flight by staying in that attitude for 3 hours, 6 minutes and 39 seconds, whereas the previous record was held by a Californian, 2 hours and 20 minutes. In case there should be any question how to classify this record, we suggest that it be placed in the same file with the record for consecutive outside loops, the record for flag-pole sitting, and the record for carrying an electric stove in an airplane for the first time in history.
