Need I explain anything? Schneider cup winning seaplane as well as appearing in what is (to me) the best Miyzaki film ever made
On Oct. 26, 1925, U.S. Army Lt. James H. Doolittle flew the Curtiss R3C-2 to victory in the Schneider Trophy Race with an average speed of 374 km/h (232.17 mph). The next day he flew the R3C-2 over a straight course at a world-record speed of 395 km/h (245.7 mph). In the Schneider Trophy Race of Nov. 13, 1926, this same airplane piloted by Lt. Christian F. Schilt, USMC, and piloted by an improved engine, won second place with an average speed of 372 km/h (231.4 mph).
