Ah, that's what I was thinking it was. Not thinking terrorism. These things just seem to have a nasty habit of blowing up every once in a while. Then again, I've always wondered why terrorists have never gone after these sorts of things. Or those massive propane tanks at propane filling stations. They seem extremely vulnerable. Those bins of bbq grill propane tanks too. Ram a car into one and you could take out an entire Lowes or HD, like what happened on King of the Hill(propane blowing up a warehouse store, not terrorism) . Really makes me worry.
Most likely wouldn't go BOOM or if it did, you'd get a fireball and blow out any glass windows & doors. You wouldn't bring down a building that way.
"Not thinking terrorism."
Well, I'm not going to automatically assume that it is, but I'm also not going to automatically assume that it isn't. Not enough information out there yet, and the public pronouncements from government officials tend to seal my impression ... an automatic dismissal of terrorism from "authorities" usually gets my radar up. A workmanlike attempt at explaining what happened, with no effort to fix a single cause is less suspect, in my mind.
