Cody carried out taxiing trials of the aircraft during September, briefly leaving the ground on the last of these. The aircraft was then returned to the workshop for the first of a long series of modifications to be made. The small ailerons were removed, a nosewheel added, the radiators moved outboard from their central position to the forward interplane struts, and modifications were made to the booms supporting the elevator. In this form, with a Union Jack flying from the strut between the upper and lower tail booms, the aircraft was presented to the press at Farnborough on 13 October. After further ground trials Cody finally judged conditions suitable for a flight trial on 16 October, and made the first recognised powered and sustained flight in the United Kingdom, which covered only 1,390 ft (424 m).
