WR-4 Hangar
Located up the street from the 1940 terminal building, WR-4 Hangar was constructed soon after the airport first opened in 1928 and is believed to be the oldest aviation-related structure still existing in Houston.
After serving successively as a maintenance facility for air mail planes, Eastern Air Lines' Houston maintenance base and eventually the 'Sky Travel' Fixed Base Operator, the hangar now provides shelter for the museum's collection of aircraft.
