It may take many visits to make the connection that yes, once airplanes did land by sea – hence, the Marine Air Terminal at LaGuardia Airport. With a clear architectural connection to the Works Progress Administration, the murals were once covered over because of their supposed connection to Communist propaganda. The circular terminal is a wonderful step back in time, like a visit to the TWA Flight Center (also an interior landmark), and today it is the “only active air terminal dating to the first generation of air travel,” state Gura and Wood in Interior Landmarks: Treasures of New York.
