Lil' Margaret is about the most perfect Mustang I've ever been around. In 12 years after her groundbreaking restoration she'd only accumulated a couple of hundred hours of flight time. The owner always had other stuff to fly (another Mustang, P-47, and Corsair), and this one just sat around being perfect, I guess. The great Corsair restorer John Lane, who was flying it this day, said it's not a great pleasure to fly, compared to the lightened "sport" version Mustangs, because Lil' Margaret is heavy and draggy -- very much like a wartime bird.
The airplane was sold into Europe a couple of years ago, and the new owner promptly wrecked it trying to take off from a short wet very soggy grass strip in Britain. He said it just didn't accelerate like he expected it to, and it ran off the end of the runway at near takeoff speed with predictable results. Duh....
