Seems to be the head scratcher for many. This could have been the point they exited a cell.
Speed seems good right up until the second the altitude heads south. Speed seems pretty accurate during climb also, data seems good so far.
Disorientation I would still not expect initially anyway, such a instantaneous fall away from a level. Loss of control entering a severe CB, I most certainly would.
Really need to know either, what they flew into, or what the engineering history is. Certainly whatever occurred, to drop like that, on the engineering front, Tail or Rear Stab something has gone wrong (or fell off as mentioned above).
