11 deceased.....that's just awful, we humans risk it all at times without fully understanding the risks, such is aviation.
It wouldn't take much of a control stick deflection to roll the machine at those speeds.I'd say it's a fair bet that the pilot was in some way incapacitated as one would need to be 100% alert & in control of such a high performance beast during the whole of the event.
Possible outcome: Trim tab failure, sudden movement by way of excessive G's created by that failure that caught the experienced pilot unawares inhibiting his abilities momentarily resulting in a few seconds of uncontrolled flight.
I now wonder what extra safety measures will be put in place for future shows?
Can't bring those deceased back but perhaps we can learn from this tragic event so their lives are not entirely wasted.
