Aerial view of what appears to be a Vickers Vimy Commercial aircraft in flight (with the unusual registration 17-X on the tail fin). The same basic airframe was used for the Vickers Vernon, adopted by the RAF as a cargo aircraft between 1921 and 1927. Photographed here in 1920, around the time of the first aerial Pageant at Hendon (July 3rd 1920). Aerofilms Collection (see Links).
