My step-grandpa met COL Holland years ago. (IIRC they both died the same year but different causes.) The old man test flew in the '60s but he was not a 'gambler' like COL Holland.

He got it past 90 degrees of bank and went into a knife edge turn where the rudder is the only aerofoil that generates a vertical component of lift. You can do that in an Extra 300 or a Pitts but not in a B52. The pilots reaction in the video was to pull back on the stick (you can tell from the massive wing flex prior to impact). In a 90 degree bank that translated into 0 increased lift and infinitely higher angle of attack.
