Only way to recover would've been to stand on the left pedal, push the throttle passed the firewal, and stick left.
But man, I don't know, 80o right bank? and 60o nose up?
Dude.
Hat's off to the guy that died doing what he loved (a moment of silence and prayers for those that loved him that he left behind).
That's not me. I want to go doing something I hate, like stuck in traffic Monday morning, doing my taxes, cleaning out the gutters, snaking the drains, sitting in the waiting room for 10 hours before the doc will see you, or something (not sliding down black-diamond snow covered-inclines at my favorite resort with waxed and polished boards strapped to the bottoms of my feets, bobbing in the gentle swell of a speedboat with the salt spray stinging my face, or making love to a beautiful woman).
We lost another mustang pilot a few weeks ago when he attempted to perform a "go'round" with full throttle... the power of the Merlin (or Allison, in the A-Model) would torque the airplane into a near snap roll. Which it did in the last incident.
Given the choice through marriage, personally would "hump" the Mustang.
It's beauty is tough to usurp. ; )
