If pallets are breaking away either we have maintenance issues or we have operation issues. Fine Air found themselves in that box and came out a loser. The FAA has a long record revoking/surrender airline operating certificates. They accomplish this achievement without help from the current NTSB/Congress in which is anti-mistakes.
I remember walking the entire length of both sides of the cargo a lot of times with the flight engineers.....the good FEs anyway who liked to check the loadmasters work.
But even though everything looks buckled/snapped/tied and locked.......cables, straps, buckles and locks also fail without warning.
I would think, hopefully, that if the plane made two take-offs, tie downs were checked at least once by the pilot(s)....... But we all know that always doesn't get done as part of the pre-flight on cargo flights.
But as "fareview" said.....there are other things that can cause a sharp pitch up and then cause that stall.....
So........I guess we'll see what the investigators find.
