The Curtiss R3C is an American racing aircraft built in landplane and floatplane form.
The R3C-1[1] was the landplane version and Cyrus Bettis won the Pulitzer Trophy Race in one on 12 October 1925 with a speed of 248.9 mph (400.6 km/h).
The other two R3C-2s, piloted by George Cuddihy and Ralph Oftsie, did not reach the finish line.
The next day, with the same plane on a straight course, Doolittle reached 245.7 mph (395.4 km/h), a new world record.
The R3C-2 that Jimmy Doolitle piloted to victory in the 1925 Schneider Trophy race is preserved at the National Air and Space Museum's Steven F. Udvar-Hazy Centre, at Washington Dulles Airport, Virginia.
