I just happened to pause it at the moment of explosion. The orange ball of flame appears to the left and back of the structure, not coming from it! It's as if a cannon was sitting there in the dark and it was fired. I will try to share my screen print...

Can't figure it out. Will make a separate post.

I can't figur out how to post a pic... it won't let me.

Anyway, as you watch the vid, keep your eye just below the light, not on the stones. I think it is a muzzle flash, and you can see a separate dustup below the light in a symmetrical pattern. Some form of artillery was rolled up there. I wonder if aerial footage would show light tracks in the grass?
