The last of the 'Bristol' aircraft was the purely research aeroplane, the Type 221. With the B.188, they furnished valuable information on the structural and aerodynamic problems associated with supersonic flight. The Type 221, first flown was on May 1, 1964, was a modified version of the record-breaking Fairey Delta 2 and used to investigate the handling and control characteristics of the slender ogival wing, which was again to feature in the Concorde.
