A test for recognition experts of an older generation, the one-off Vickers fighting Biplane Type Eight of November 1915. Although apparently big, the F.B.8 had a wing span of only 38 ft. 4 in. (8 in. less than the Hawker Sea Hawk), but while fast for its day (98 m.p.h.), the F.B.8 was cumbersome, and this two-seater was soon abandoned. The gunlayer stood in the nose and fired a single .303-in. Lewis gun

The Vickers E.F.B.8 fighter powered by two 80 h.p. Gnome rotaries. Note the oil slinger rings around each engine.
