The American Eagle A-1 was designed in late 1925 as a training aircraft to replace WWI biplanes, such as the venerable Jenny, then in use by the Porterfield Flying School. The prototype A-1 first flew at Richards Field in Kansas City, MO on 9 April 1926. Small modifications made to the design in 1927, including ailerons on the lower wings, led to the A-101 designation and approximately 300 in total were built. It is on display at the Yanks Air Museum.
