I've been pondering the development of Aviation and it's related technologies and I think that various Countries around the world have each made their own unique contribution to the area. I offer a couple as the start of a list, please feel free to comment, argue, add your own thoughts.
1. United States of America, Orville and Wilbur Wright; inventing and building the world's first successful airplane and making the first controlled, powered and sustained heavier-than-air human flight, on December 17, 1903.
2. United Kingdom, Robert Watson Watt; Radar On February 26, 1935, a Handley Page Heyford bomber flew along a path between the receiving station and the transmitting towers of a BBC shortwave station in nearby Daventry. The aircraft reflected the 6 MHz (49 m) BBC signal, and this was readily detected by Arnold "Skip" Wilkins using Doppler-beat interference at ranges up to 8 mi.
