The Greater St. Louis Air & Space Museum is a museum with the mission to preserve and display historic air and space craft and artifacts, and provide educational programs.

The museum is housed in the Curtiss Wright Hangar number two at St. Louis Downtown Airport, Cahokia Heights, Illinois.

The brick structure featured a cast Curtiss Wright emblem across the doorway.

Its Ford 4-AT-B was used for corporate transport and line patrols, and is now part of the National Naval Aviation Museum.

In 1939, Oliver Parks expanded his flight operations to the airport for the Civilian Pilot Training Program.
