Probably wouldn't have ignited even if they did. Would have needed a secondary ignition source.
I'm not construction expert or metallurgist, but I'd imagine tanks that size are pretty sturdy from impacts. Might not have been designed with gunfire in mind, but I'd imagine the walls are fairly thick with the amounts of gasoline they store.
Regardless, the old adage of warhead versus armor comes into play. Thicker steel of the tank? Larger warhead and it's a good thing this turd wasn't shooting anything .50 big bore. Because you can still get APIT for the .50 BMG.
I'd bet they are double walled since they do not have a secondary containment dike around them. Or at least one I have seen. ASTs have to have secondary containment usually 110% of the capacity of the largest vessel for fuel storage.
Did he purposely fire at them or did the rounds just happen to hit there?
Again, I'm no expert in the construction of same. But if he was using something larger like a .50 rifle, that could have made a big time mess. Basically, you've got fuel tanks sitting in the Nevada heat all day putting off fumes inside that tank. You hit said tank with an armor piercing incendiary round and you're going to get a massive blast from the fumes. It would have been better if it was full believe it or not.
Kind of an assumption on my part on that bit, but unless there is a neutral gas like nitrogen pumped in to prevent that kind of thing from happening, I could see a half empty tank being all kinds of trouble.
Depends on what fuel is in those tanks, jet A is pretty much like kerosene but av-gas, yeah you might get a boom.
A couple of new and important details emerged today. First, Patddock shot a guard in the leg about six minutes before he opened fire on the crowd when the guard came by to check out an alarm that the door had been left open. Second, there is no evidence of any additional shooters.
Those facts should cause the conspiracy loons to pause with inane speculation about this being other than what it appears to be.
Help in what sense? Helped him change a flat tire on his way to Vegas or knew what he was going to do and helped him get the firearms or set up?
If the latter, why? For what point, that no one is making.
Of course the latter. None of this even makes any of your Spidey senses tingle?
The target, the methods, the planning, the weaponry. Nothing?
Hell, the simple fact a highly successful man with more than a few things going for him suddenly snapped, surveilled that target (and possibly more) for several days before striking should be enough for you to raise the "that's really odd" angle.
My point exactly. This reeks of terrorism, but completely minus the manifesto that normally goes along with it. I'm not entirely discounting the possibility of a lone wolf attack, but damned if I can figure out the "why" of it all.
