There were still few passenger airlines in America in 1928 and here mail on route CAM-1 from New York is delivered to Boston by a new PA-5 mailplane. CAM-1 was contracted to Colonial Air Transport, who apparently hired this aircraft. Pilot Ray Wonsey is known to have flown a Mailwing for Colonial around this time. NC3468 was registered to Phineas Millis, the owner of an airfield in Mendon, Massachusetts in 1928. Note logo of American Railway Express. This was a package delivery service like UPS or DHL, which did not operate aircraft itself. Photo by: Leslie Jones / Boston Public Library
