COMMENT: The Martin-Maker M.B.5, developed on the basis of the Martin-Baker M.B.3, was considered by many to represent the extreme limit of piston-engined fighter development. Apart from its superlative performance and handling characteristics, the M.B.5 had a number of outstanding qualities and the general design and layout was excellent and infinitely better than any other similar type of aircraft. It first took-off into the air on May 1944. Although all pilots who flew the M.B.5 in the following time were fulsome in their praise of its qualities it was not put into production, remaining one of the minor mysteries of the war (Ref: 12).
