Actually, it looks like an old fashioned high-speed stall to me. But you know more than I do.

It may have been. Once it was inverted, his pulling positive G was the end. I would've been thinking that a push to inverted flight at that point and maintain altitude until stabilizing the roll snatching, as it looks as if it does a bit of twitching in roll throughout the maneuver, then a recovery half roll to upright.
In another film, the one on CNN, as the Bearcat goes by I see Stu Dawson (Bear pilot this year) rolling wings level and then back and forth, totally uncharacteristic at that point on the course where they are usually locked into a left bank. This is at the same time as the accident maneuver of the Mustang. I wonder what the connection of these two odd attitudes by the two racers means. They must have had a close call, a near miss, an unusual thing for them both. We need, and I'm sure there is, a film of the back straight along the valley of speed into turn eight where all of this will be revealed.
