The Curtiss JN-4 biplane is possibly North America's most famous World War I airplane. It was widely used during World War I to train beginning pilots, and was known in Canada as the "Canuck", and in the U.S. as the "Jenny". It was a twin-seat (student in front of instructor) dual control biplane. Its "Pulley" front engine and maneuverability made it ideal for initial pilot training with a 90 hp (67 kW) Curtiss OX-5 inline engine giving a top speed of 75 mph (121 km/h) and a service ceiling of 6,500 ft (1980 m).
