On August 29, 1917, Captain Marquis Giulio Laureati flew in an S. I. A. from Turin to Naples and return, a distance of 920 miles, establishing a new non-stop flight world’s record, and a month later he and his mechanic flew from Turin to London, crossing the Alps at an altitude of 12,000 feet and negotiating a distance of 656 miles at an average speed of 89 miles an hour. The speed, however, was not remarkable, for 100 miles an hour is the average speed for big machines, and 150 miles was made by scouting-machines on the West Front during the war. On April 19 Captain E. F. White, U. S. A., in a DH-4, flew from Chicago to New York, 727 miles, without stopping, in six hours and fifty minutes. On April 25, 1919, four naval aviators, in a seaplane of the F-5 type, Serial No. 3589, made a new world’s record for an endurance flight when they flew, officially, 1,250 miles in twenty hours and ten minutes. The record was made during a continuous flight from 11.42 A. M. April 25 until 7.52 A. M. April 26. Throughout the entire afternoon and night, and often bucking a strong breeze over the Chesapeake Bay and the Virginia Capes, the F-5 described a great circle, extending northward to the mouth of the Potomac River and then eastward to the Atlantic Ocean, sweeping over the Capes and then inland to the naval station. The four men in the machine ate three meals during the flight. The machine left the naval base with 850 gallons of gasoline. When it landed there was scarcely two gallons in its tanks. The F-5 is an improved type of flying-boat that the Navy Department intended using in patrol duty for war purposes. It has a wing spread of 105 feet. The machine was built by Curtiss, and is known as a “kite boat,” equipped with twin Liberty motors.
