U.S. naval aviation began with pioneer aviator Glenn Curtiss who contracted with the United States Navy to demonstrate that airplanes could take off from and land aboard ships at sea. One of his pilots, Eugene Ely, took off from the cruiser anchored off the Virginia coast in November 1910. Two months later Ely landed aboard another cruiser, , in San Francisco Bay, proving the concept of shipboard operations. However, the platforms erected on those vessels were temporary measures. The U.S. Navy and Glenn Curtiss experienced two firsts during January 1911. On 27 January, Curtiss flew the first seaplane from the water at San Diego Bay and the next day U.S. Navy Lt. Theodore G. Ellyson, a student at the nearby Curtiss School, took off in a Curtiss "grass cutter" plane to become the first naval aviator.
