The June Bug (or Aerodrome #3) was an American "pioneer era" aircraft designed and flown by Glenn H. Curtiss and built by the Aerial Experiment Association (A.E.A) in 1908. The June Bug is famous for winning the first aeronautical prize ever awarded in the United States, the Scientific American Cup. Design and development The competition offered a solid silver sculpted trophy, and $25,000 in cash, to be awarded to whoever made the first public flight of over 1 kilometer (3,280 ft). Glenn Curtiss had a passion of collecting trophies so he and the Aerial Experiment Association built the June Bug with hopes of winning the Scientific American Cup. Aerodrome #3 included the previously used aileron steering system, but a shoulder yoke made it possible for the pilot to steer by leaning from side to side. The varnish that sealed the wing fabric cracked in the heat, and so a mixture of turpentine, paraffin, and gasoline was used. The June Bug had yellow wings because yellow ochre was added to the wing mixture in order to make the aircraft show up better in photographs, due to the solely orthochromic-form monochrome photographic techniques of that time. It was named by Alexander Graham Bell after the common Phyllophaga, a beetle known colloquially in North America as the "June bug," because June bugs were observed to fly similarly to aircraft: they have large stiff outer wings for gliding, and more delicate smaller propeller-like wings that do the actual propulsion. The June Bug was tested in Hammondsport, New York, at Stony Brook Farm. Curtiss flew it successfully on three out of four tries on June 21, 1908, with distances of , , and at . On June 25, performances of and were so encouraging that the Association contacted the Aero Club of America about trying for the Scientific American Cup. Operational history Cup attempt The Aero Club contacted the Wright brothers, offering them the chance to make an attempt first. Orville wrote to decline the opportunity on June 30, as the Wrights were busy completing their deal with the United States government. The message was received by July 1, and Curtiss took to the air as requested on July 4 (Independence Day). The flight was a great public event, bringing people in from all directions. The event was overseen by a delegation of 22 notable members of the Aero Club, headed by Alan R. Hawley.
