FOX news just had an aviation expert who said that the wing tanks are "self sealing" in case of crash.
Self-sealing? For a bird-strike maybe, but not if they are ripped apart.
;-)
If I were you folks, I would wait for Boeings and the Asiana flight crew and flight attendents to be debriefed on description of the incident. That fire in the cabin is suspect....although the center fuel tank could have ruptured on the hard landing. What bothers me is the blowout of the aft pressure bulkhead in rearward fashion. Strange!!! Conclusions are a long way off!!! Passengers also, will have valuable verbal input as to what occurred in the interior cabin and aircraft exterior. Time to remain calm & research. The truth will surface as it always does in most instances.
