Wg Cdr Ken Wallis flying the recently-completed replica of the 1909 Wallbro Monoplane. The original Wallbro was built and flown at Cambridge by the Wallis brothers, and the replica was made by their sons. Registered G-BFIP, it first flew on August 11, 1978 at RAF Swanton Morley. Like the original, the airframe is of steel tube.

Ken Wallis' speed record-holding autogyro, G-BLIK, with his flying replica of the 1910 Wallbro Monoplane - the first aircraft built by a Wallis. The pair were photographed at Swanton Morley on May 16, 1985, 75yr to the day since the original Wallbro's first public appearance.
