Perhaps the best video in terms of timing and angle:

Obviously, something (allegedly fireworks) were on fire well in advance to the mushroom cloud explosion. We can also see what looks like several little flashes in the smoke prior to the big bang.

It does look like fireworks at the beginning, but something else went boom from the looks of it.

I kind of doubt the people videoing this were expecting much more. I sure hope there’s not too many injuries from the broken, flying glass. That’s nasty.

The hospitals are going to be overwhelmed with this one.
