Flight from a ship

In 1910, the first airplane flight from a ship was made by Eugene Ely from the bow of the scout cruiser Birmingham, anchored at the Hampton Roads Yatch Clubhouse at Willoughby Spit. His runway was 83 feet long, with a five degree slope, but because the plane itself was 57 feet long, the available runway for takeoff was only 26 feet. He then flew through fog and rain to Hampton Rpads, Va. For his effort, he won a $5,000 prize offereed by John Barry Ryan. Ely was a civilian pilot for the Curtiss Aviation Company. The following year, 18 Jan 1911, Ely made another first in history when he landed on the battleship USS Pennsylvania in San Francisco Bay.
