NC19903 poses for the camera over Mount Rainier, Washington, before delivery to Pan Am in 1940.

After spending more than two decades at the Pima Air Museum, this aircraft is now preserved in the Smithsonian Udvar-Hazy Center at IAD. Obtained from PAA 60 years ago.

Returned to TWA in 1945 as NC19906. Used on US regional services. Sold in 1951 to Aigle Azur as F-BELU. From TWA 60 years ago.
