The Whitehead No.21 was the aircraft that aviation pioneer Gustave Whitehead claimed to have flown near Bridgeport, Connecticut on August 14, 1901. Professional aviation historians and scholars reject claims for the flight. A description and photographs of Whitehead's aircraft appeared in Scientific American in June 1901, stating that the "novel flying machine" had just been completed, and "is now ready for preliminary trials". The flight was reported in the August 18, 1901, issue of the Bridgeport Sunday Herald and reprints or rewrites were published in many other newspapers.
