Aerial Experiment Association / Curtiss June Bug / Loon
The June Bug was a further refinement of White Wing, was sponsored by Curtiss and was more successful with the same 40 hp lightweight V-8 engine. First flown on 21 June, it made numerous flights, including a straight run of 1042m on the seventh flight. On 4 July1908, Curtiss made a pre-arranged flight to win the first task, or 'leg', of the Scientific American Trophy, which called for a straightaway flight of one kilometre. After a couple of false starts, he won this with ease by flying 1.6km at a speed of 62.76km/h.
The June Bug was used by Curtiss for a total of 32 flights. It then crashed on 2 January 1909 and went into retirement.
Curtiss fitted pontoons to his June Bug, renamed it Loon, and tested it in June 1909, but it would not leave the water.
