On 8 September 1909 he made a flight lasting over an hour, covering around 40 miles (64 km), landing because he was out of fuel. He also flew the aircraft at the Doncaster Flight Meeting in October 1909. Although he did not win any of the prizes on offer, Cody made use of his appearance to publicly take British citizenship on 28 October, and promptly entered his name for the "Daily Mail" prize for the first British aircraft to make a circular flight of over a mile. However, the Doncaster meeting had not been sanctioned by the Royal Aero Club, and so any flights made there could not be officially ratified, and the prize was eventually won by J.T.C. Moore-Brabazon on 30 October.
