The Curtiss Jenny acquired its name from the earlier J and N model trainers, which were the bases for its design. The Curtiss JN was built to serve the US Armed Forces with the first unit rolling out of the factories in 1915. Though the aircraft series was well-received, the earlier variants faced a lot of problems. This is especially true for the JN-2 which was deficient in terms of performance because of its weight. As such, the succeeding variants aimed to address these concerns bit by bit. The JN-4, in particular, was the variant that spearheaded the series’ success. It was a twin-seat biplane powered by a 90hp Curtiss OX-5 V8 engine. It had a maximum speed of 75mph and a ceiling of 6,500ft. When the Curtiss JN4 entered military service, it arguably became the most famous World War I aircraft.
