Editing Tractor configuration (section)

==Origins==
The first successful airplanes to have a "tractor" configuration were the 1907 [[Santos-Dumont Demoiselle]] and [[Blériot VII]].

The first biplane airplane to have a "tractor" configuration was the [[Goupy No.2]] (first flight on 11 March 1909) designed by [[Mario Calderara]] and financed by [[Ambroise Goupy]] at the French firm [[Blériot Aéronautique]].<ref>Mario Calderara, Commander Calderara Glances Backward and Ahead, U.S. Air Services, Volume 15, Air Service Publishing Company, September 1930, page 38</ref> It was the fastest airplane when it was made.<ref>{{Cite web|url=http://www.treccani.it/enciclopedia/mario-calderara_%28Dizionario-Biografico%29/|title=Calderara, Mario in Dizionario Biografico|website=www.treccani.it}}</ref> At that time a distinction was made between a propeller ("pushes the machine", akin to a ship's propeller) and a tractor-[air]screw ("pulls the machine through the air").<ref>{{Cite magazine|url=http://www.flightglobal.com/pdfarchive/view/1910/1910%20-%200319.html|archive-url=https://web.archive.org/web/20150924153754/http://www.flightglobal.com/pdfarchive/view/1910/1910%20-%200319.html|archive-date=24 September 2015|title=Propellers and tractor-screws (reader's question and editor's answer)|id=475|magazine=Flight|date=23 April 1910}}</ref> The [[Royal Flying Corps]] called the tractors "Bleriot type" after [[Louis Bleriot]], and pushers "[[Farman Aviation Works|Farman]] type".
