The Rex Smith Biplane was a pioneering biplane based mostly on designs of Glen Curtiss. It was built and demonstrated at College Park, Maryland, at the same airfield that the Wright Brothers trained pilots using their aircraft for the U.S. Army Signal Corps just north of Washington, D.C. This followed the initial demonstration at Fort Myer, Virginia, in 1908 and 1909, when the U.S. Army Signal Corps accepted the Wright Flyer in July 1909. Both the Wright Brothers and Curtiss continued to demonstrate their aircraft at the College Park Airport.
