P-51 Mustang
Designation: P-51D
Why it matters
The P-51 Mustang was the fighter that won the air war over Europe. When the British Merlin engine replaced the original Allison, it transformed from a good aircraft into a legend. The Mustang could escort bombers all the way to Berlin and back — something the Luftwaffe never expected. That range, combined with its performance at altitude, broke the back of German air defense. The distinctive rumble of that Merlin engine is the sound of victory.

Patina notes
Surviving P-51s show their age in subtle ways. Original aluminum skins develop a particular sheen from decades of polishing. Cockpits show wear patterns from thousands of hours of pilot hands on controls. The challenge with warbirds is balancing preservation with airworthiness — too much patina and they can't fly, too much restoration and history is erased. The best examples maintain the evidence of their service while meeting modern safety requirements.
Preservation reality
About 175 P-51s remain airworthy worldwide. They're expensive to operate — figure $3,000+ per flight hour for fuel, maintenance, and insurance. Most are owned by wealthy individuals or foundations. Annual inspections alone run five figures. The Commemorative Air Force and other organizations fly them for public display, keeping the memory alive for new generations.
