Agree'd Frank. Bummer. I'd like to see that. Looks like the made some sort of containment structure around and over it. (Trying to mitigate shrapnel?) When it lit off it appears that it made quite the show! I'd buy a ticket for that show. You don't get to see that that often. (Well , in peace time.) Would not want to be on the receiving end during war time either. Ant body else know about this kind of stuff?
