Despite the emphasis in the press on speed, the Air Service also established a number of altitude, distance, and endurance records. The Packard-Le Peré LUSAC-11 biplane set world altitude records over McCook Field of on February 27, 1920, by Maj. Rudolph W. Schroeder; and on September 28, 1921, by Lt. John A. Macready. A distance record was set by Capt. St. Clair Streett leading a flight of four DH-4s from Mitchel Field, New York to Nome, Alaska and back, a distance of 8,690 miles (14,000 km), between July 15 and October 20, 1920. Flying across the northern United States and southern Canada in 15 legs, the flight reached Nome on August 23 in 56 hours of flying time, but was prohibited by the U.S. State Department from completing the first flight to Asia across the Bering Strait. The first nonstop endurance flight across the U.S., made in 26 hours and 50 minutes at an average speed of 98.76 mph, was made May 2–3, 1923, from Roosevelt Field, New York, to Rockwell Field in a Fokker T-2 transport monoplane by Macready and Lt. Oakley G. Kelly. The feat was followed in August by a flight in which a DH-4 stayed aloft for more than 37 hours by means of aerial refueling. The Fokker T-2 is on display at the National Air and Space Museum in Washington, D.C.
