I came across this at an airshow event I attended and was struck by it, so I figured I would share with like-minds.
Note the beautiful discoloration on the airskin from the flame exhaust of the muscle that is a Packard V-1650-7 Merlin. The liquid-cooled Rolls-Royce V-12 piston engine was capable of well over 1,300 hp probably contributed more to the defeat of the Germans over Western Europe than any other single mechanical invention.
The beast powers a TP-51C Mustang owned and operated by the Collings Foundation. Born as P-51C 42-103293 “Betty Jane” to North American at its Dallas Facility, the plane was restored and converted in 2002 to a 2 seat version of the P-51C and is an airshow regular.
