The pics of the tail on the ground do not show the horizontal stabilizers still attached or near the remaining tail.

Structural failure resulting in loss of the horizontal stabilizers can cause the excursions noted.

Also, the main fuselage appears to have impacted flat and inverted, while the tail impacted upright. Loss of HSs usually causes the nose to tuck and aircraft to go inverted, sometimes resulting in a flat spin.

Until I re-read your comments, I overlooked your mention of an earlier tail strike. Except for the missing overhead in the rear latrine area, I can see that being a matching failure cause, as well...

Of course, I agree with your remarks re loss of HStabs. Sort of a chicken and egg thing, though: Did loss of HStabs cause a high-stress condition -- or vice versa...?

If the examiners/analysts are any good, the FDRs should shed some light on those issues.

Whatever the cause, that Radar24 data shows a radical departure from stable flight -- to put it mildly...

Agreed. I believe I mentioned that the wild vertical delta vee excursions could have been porpoising and/or tumbling...

BTW& FWIW, I didn't see (except in a photo of a different crash) signs that the rest of the a/c landed inverted. I'll look more closely...
