Tested

The Loening Amphibians to be used in the MacMillan expedition (TIME, Apr. 20) passed their tests last week, after a highly satisfactory flight from Mitchel Field, L.I., to the Naval Air Station at Anacostia, Washington, D.C, and were formally accepted. In acceptance trials, the OL-1, as the Amphibian is officially designated, attained a height of 14,000 ft, made a speed of 125 mi. per hour and climbed more than 5,000 ft. in ten minutes. Fully loaded, the plane weighs 5,200 lb., and carries a crew of four men. With its inverted engine giving the pilot clear vision ahead; its retractible gear allowing the plane to alight on ship deck, on land, on sea, or to roll up a beach under its own power; with its photographic, wireless and heating arrangements, the Loening is the last word in airplane construction.
