Engineering and Technology in WW1

William Barker, as I’m sure you know, took on and defeated several Fokker DVII’s in his final combat when flying a snipe, I’ve also read that the Martinsyde Buzzard in it’s final form was superior to the DVII. I’m sure that the technological and engineering race which began with the Maurice Farman and ended with the Sopwith Snipe would have continued, but with the added industrial muscle of the U.S.A.
I’m not aware of any competitive American designs however. Although Wilbur and Orville showed the way with powered flight I would have thought the U.S designers would have faced a steep learning curve to catch up with the likes of Folland and T.O.M Sopwith.
