from the AKI press site:
http://static.akipress.org/photo/aviacatastrofa/14.jpg
seems to show some large forcible penetrations formed at some point in the incident. (and, no, I am not trying to imply what formed them, nor that they are any any way causal, but they seem unusual to me)
Currently url's like that shown numbered 1 through 14 all relate to this incident.
Thanks for the link
I agree, unusual and significant. I don't see some of these pics as being post impact. In some of them there appears to be through holes in the wing structure. But I'll see what others say before I form a stronger opinion.
It would be interesting to see more photos of the general wing to tell if it was intact when it landed.
