The June Bug (or Aerodrome #3) was an early US 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, the Scientific American Cup, ever awarded in the United States.
A solid silver sculpted trophy, and $25,000 in cash, would be awarded to whoever made the first public flight of over 1 kilometer (3,280 ft). Glenn Curtiss had a hobby of collecting trophies, and he and the Aerial Experiment Association built the June Bug with hopes of winning the Scientific American Cup.
On July 4, 1908, the airplane successfully flew 5,360 ft (1.6 km) in 1 minute 40 seconds, winning the trophy and cash prize.
