What should the pilot have done to achieve this? Do you assume they were
manually flying aerobatics at that point in time, when they were suddenly incapaciated during the maneuver???
You can safely assume they were on Autopilot before this (whatever it was) occured.
What happened then will hopefully be answered by the FDR/CVR.
At the moment nothing can be really ruled out.
Structural failure (e.g. incorrect repair of wingtip?)
Failure to mind the store while AP disengaged/did strange things.
Explosive device.
CWT explosion.
Suicide.
FCS problem.
x other scenarios.
Although some might be more likely than others.
We will know for sure when they found and analysed the recorders.
Until then I'm afraid the only thing which might become clearer somewhat sooner is if it disintegrated at altitude, once the wreckage has been found.
