Wasn’t... This was a ground burst. Longer videos show a fire started, there were sparks flying off it. Either ammo cooking off or fireworks igniting. Then something big cooked off and the whole thing blew out.
My money is on a shipment of fireworks/ammo/powder coming in and was either accidentally, or on purpose, set on fire.
Why bomb something if there is already something there that will go boom?
Reminds of 1983, I was there.
Tell you one thing though. It was really something hey?
Like the one in Vegas years ago.
Even at a ground burst, a nuke would send out a flash of light that would blind anyone who happened to be looking that way.
This one had a fire going-like you said, and then it touched off something.
