Suspended in the NASM Golden Age of Flight Hall. Built in 1927, this Mailwing was the prototype for Pitcairn mail planes that led to the creation of Eastern Air Lines. First use of the type as a mail plane was by Texas Air Transport on Contract Air Mail Route 21. The PA-5 was successful on the CAM 19 New York-Atlanta route, flying mail by night in seven hours, one-third the time it took by train. Eastern Air Lines used this aircraft till 1934. It was sold and converted to carry passengers, being repurchased and restored as a gift for Capt. Eddie Rickenbacker till donated in 1957 to NASM.
