Tried to post some pictures, wouldn't let me. From the pictures it does appear the tail section is inverted, but it is hard to tell if it hit that way, though I would guess it did. The remainder of the fuselage is in the house. Unfortunately, the rooms that took the direct hit in the rear is where the 13 year old and the baby were. The mother was at the front of the house, and along with neighbors and off duty firefighters who lived nearby made multiple attempts to get to the kids.
Accounts from friends and colleagues who were working, including one who was on the first due engine, is that the scene was unimaginably horrific, complete with having to forcibly remove the mother who was screaming for her kids. Several veteran guys described it as one of the worst runs of their careers.
The metars at the time weren't all that bad at first glance, but there was a vigorous weather system in the area. As others have said, that's a challenging approach on a good day.....
