The RCAF acquired several war-weary B-17s for use as trans-Atlantic mail planes. Despite being described as dilapidated when delivered and suffering several accidents including a midair collision between Prestwick and Gibraltar, 9205 continued in service until December 1946. It was sold in Argentina as LV-RTP and finally scrapped in 1964. Photo from: Library and Archives Canada

Although marked as RR-5 Bureau Number 9205, this is actually 4-AT-E N7861 which never was assigned to the US Navy. It was originally built in 1928 as a 4-AT-B and converted by the factory in 1929 to a 4-AT-E. N7861 spent most of its flying career with Johnson Flying Service, where it was used as an insect spray aircraft as well as under contract with the US Forest Service as a smoke jumper transport. It was donated to the museum in 1973. The US Navy and US Marine Corps had a total of 9 Ford Tri-Motors of various types in their inventory, all ordered between 1927-1931.
