    Curtiss XF6C-6 Racer in 1930

    U.S. Marine Corps. pilot Captain Arthur H. Page sitting in the Curtiss XF6C-6 Page Racer on August 18, 1930. The aircraft featured a Curtiss Conqueror V-1570 racing engine, the last of the Curtiss liquid-cooled engines. On September 1, 1930, Captain Page flew the aircraft in the Thompson Trophy Air Race at the National Air Races in Chicago. While leading the field, the aircraft lost power, and Page died during the resulting forced landing.

The Conqueror developed from a history of Curtiss engines beginning in the early twentieth century. It was the last of Curtiss liquid cooled engines. The U.S. Navy purchased this engine in 1930 and installed it in the Curtiss XF6C-6 Hawk, a biplane converted to a monoplane racer. On September 1, 1930, U.S. Marine Corps pilot Capt. Arthur H. Page Jr., flew the aircraft in the Thompson Trophy Air Race in Chicago. While leading the field, the aircraft lost power, and Page died during the resulting forced landing.

To determine what happened, the Navy's Aeronautical Engine Laboratory disassembled and inspected the engine. They determined that the magneto drive shaft bushing and housing failed, which most likely retarded the magneto timing enough to cause a loss of power and engine failure. While historians have speculated that Page was overcome by fumes and crashed, the official Navy report indicated otherwise.
