Roy and Margaret Thrush Commercial Airlines Collection

Identifier: 2019-09-10
The Roy and Margaret Thrush Commercial Aviation Collection is a small collection that focuses mainly on Roy Thrush's 20-year career as a commercial pilot for TWA with a much smaller focus on his brief time at Lufthansa. The bulk of the collection is textual documents, including pilot logs; employee documents, including correspondence, memos, and schedules; membership cards; and a partial TWA pilot's manual. There are also 16 photographs, most of which depict aircraft. Identified aircraft include the Douglas DC-2 and DC-3 in TWA livery. A few images feature Roy Thrush in his pilot uniform and with aircraft. One photocopy of a photograph shows Thrush with a TWA stewardess, likely his wife Margaret. There is also one 10x12 inch lithograph of a Boeing 307 Stratoliner. Two items pertain to Margaret Thrush, including an undated TWA stewardess recruitment brochure and a photocopy of a retrospective article about Thrush and her experience as a flight attendant with TWA from 1937-1944.
