The pilot was McKittrick. Apparently, he bounced a landing, applied too much power, and torque-rolled it (local assessment). Tragic, and he had just recorded several perfect landings with an instructor in the plane; it had dual-controls, and did just fine.
If you are an instructor, have a student who does it right 3 to 5 times in a row, just before soloing, you tend to let them have a go at it solo. In this case, the student simply mismanaged the power on the go-around.
Maybe a bounced-landing go-around should be practiced several times before solo? Maybe, even probably, it WAS.
In any case, tragic. I have a friend who has 30 or so solo hours his own, new, baby P-51 and he has no trouble with this, mostly due to practice of same.
Wish Mr. McKittrick had the same experiences with the aircraft ...
