New R.A.F. Types: XXI.—The North American Mustang

THE NA‐73 (P.51) Mustang was produced in 1940 and is now going into service with the R.A.F. It differs considerably from earlier North American types, in that it is long and slender instead of being short and fat. In fact, the slender lines, coupled with the “squared” main and auxiliary surfaces, are reminiscent of German rather than U.S. design.
