The P-51D, which I flew, was a very straightforward airplane in every way. By that I mean it wasn't difficult to fly or hard to handle, as long as you remembered a few basic things.
First and foremost, you never forgot for a minute that it could bite hard if you got careless.
There are lots of airplanes that will let you have another chance if you get ham-handed. The -51, in certain areas of her envelope, wasn't one of them. I remember telling everyone I ever checked out in the Mustang to take it up high, lower the gear and flaps, then back it off to about 15 inches with the prop up to 3 grand....slow it down easy to about 130 mph...then SLAM in 61 inches fast....
The resulting torque roll might have helped save a few lives on full power go-arounds. None of my guys ever torqued one in anyway.
