The Cradle of Aviation Museum is an aerospace museum located in Uniondale, New York on Long Island to commemorate Long Island's part in the history of aviation. It is located on land once part of Mitchel Air Force Base which, together with nearby Roosevelt Field and other airfields on the Hempstead Plains, was the site of many historic flights. In fact, so many seminal flights occurred in the area, that by the mid-1920s the cluster of airfields was already dubbed the "Cradle of Aviation", the origin of the museum's name.
