THE SHORT "PUSHERS."—In 1909 came the semi-Wright biplane, with 35 h.p. Green, on which Mr. Moore-Brabazon won the "Daily Mail's" £1000 prize for the first mile flight on a circuit on a British aeroplane. Then the first box-kite flown by Mr. Grace at Wolverhampton. Later the famous "extension" type on which the first Naval officers learned to fly. Then the "38" type with elevator on the nacelle, on which dozens of R.N.A.S. pilots were taught.
SHORT TRACTORS, 1911–1912.—They were all co-existent, but the first was the "tractor-pusher" (bottom of picture). Then came the "twin-tractor plus propeller" (at top). A development was the "triple-tractor" (on the right), with two 50 h.p. Gnomes, one immediately behind the other under the cowl, one driving the two chains, the other coupled direct. Later came the single-engined 80 h.p. tractor (on the left), the original of the famous Short seaplanes.
