Then I haven't seen any picture of floor. It seems that seats were shedded off the floor one by one.
Quite a remarkable number of seats are found without seat-rails. Most triple seats (these seats are connected at the back with a sturdy tube ... diameter looks like about 5 cm). There is one picture of 2 rows of 3 seats that are still connected to their seat-rails. I have seen some seat-rail fragments. The pictures showing paxdoor3 left have parts of the floorgrid visible.
