THE VICKERS "VULCAN," 360 H.P. ROLLS-ROYCE "EAGLE" ENGINE. - This machine was described and illustrated in detail in our issue of May 4, 1922, but photographs have not been available until now. The machine carries eight passengers in a roomy cabin, and will shortly be put on the London-Brussels service by the Instone Air Line.

THE VICKERS "VULCAN" COMMERCIAL MACHINE: Three-quarter rear view. A feature of this machine is the exceptionally low landing speed of 40 m.p.h., and the quick pull-up after touching. The "Vulcan" also gets off after a very short run, and climbs steeply. The power expenditure is only 45 h.p. per passenger carried, so that the machine should be very economical.
