Colonel, I tend to agree. If the container is ruptured/torn, then the force required to do that must surely have come from within indicating explosion possibly caused by DG's.
I don't see a rush of air past the container causing it to fail; it may be that there is damage to the other side as well, and then the damage may well have been caused by an outrush of air taking the path through the container.
Width only small pics to see the damage, it is difficult, if not impossible, to make any sort of determination.
I hope it can be tracked back to maintenance, or lack of, for the engineers sakes. The reasons are twofold; if it wasn't a maintenance issue then they have egg on their faces over their claims that QF mgt are at fault over outsourcing services, if it is,then they look good and have a case for what they're chasing.
And yes, any sort of credit from the CEO was conspicuous by its absence, although it's what we train for every few months, and is public credit due?
