I have seen reports and animations of both and understand there are many ways this can happen, but actually go several hundred feet near vertical and hit the runway.

Reports state that there was a go-around prior, maybe this was a second, which would make sense being aligned over the runway at several hundred feet.

Since this plane was of the era of Boeings rudder issues and the is has been leased to various third world airlines after the issue was quantified, could it be that the problem was never retrofitted?

Hopefully the Russian investigation will be thorough and valid.

RIP poor soles.
