A-1 Triad (Indoor)

Ordered 8 May 1911, the A-1 Triad was the Navy's first aircraft and one of the earliest hydroaeroplanes (floatplane). Built with retractable landing gear, the A-1 could operate from land, sea and air. The Navy used the A-1 for early training and aviation experiments, including the first attempted catapult launch. Over a dozen similar aircraft built by Glenn Curtiss served as the Navy's premier floatplane trainers until the introduction of the Curtiss N-9 in 1916.

It was upon the wings of the A-1 Triad, the Navy's first aircraft, that U.S. Naval Aviation took flight. The Navy requisitioned the airplane in May 1911, just months after civilian pilot Eugene Ely successfully demonstrated that an aircraft could operate from a ship. Yet, it was the A-1's builder, pioneer aircraft manufacturer Glenn Curtiss, who convinced the Navy of the airplane's utility for naval purposes. He did so by flying an early floatplane to a ship and landing on the water alongside it. The airplane was then brought aboard and put back over the side by crane, demonstrating that an aircraft could be launched and recovered from a standard ship.

The A-1's nickname derived from the fact that in addition to flying, its pontoon float and retractable landing gear allowed it to operate from both land and water. The A-1 was the aircraft in which the Navy's first aviators learned to fly. As would be expected of the Navy's first aircraft, the Triad was the platform for early experiments, including making the first night water landing without the benefit of landing lights, tests in airborne wireless communication, and a cross-country flight covering a distance of 112 miles in 122 minutes. It also participated in early catapult trials, though both Naval Aviator No. 1 Theodore Ellyson and the aircraft plunked into the Severn River during the first test launch on 31 July 1912. It proved just one of many minor accidents encountered during the airplane's service, but the A-1's luck eventually ran out. After 285 flights and numerous rebuilds, it was damaged beyond repair in a crash on 6 October 1912.

The aircraft on display is one of two replicas built by the Institute of Aerospace Sciences in San Diego to commemorate the Golden Anniversary of U.S. Naval Aviation in 1961, the work of some 130 volunteers and a few employees of the Overhaul and Repair Department on board NAS North Island, California.
