Explosion from flammable gas/fluid makes the most sense as culprit here.

Lot of stuff to me doesn't make sense as pertaining to safety. Not trying to change the subject, but look at the hurricane right now and all the chaos associated with it. You'd think by now we'd have our act together.

Back to this tragedy......too late to help these people but I hope at least something productive comes out of it wrt mitigating future incidents.
