Greg posted some great video that one of the crewmembers, Cassie, took during the fireworks show we did this year. It’s pretty cool.  About 1:15 into the video, it zooms down and you can see the line of mortar racks and four people standing a few yards back from where it’s all going off.  I’m standing in that group with a road flare on the end of a stick (not lit), waiting to ensure that everything goes off.  (If one of the shells doesn’t go off electronically, I get to light up the flare and run out and light it by hand.  Fortunately that didn’t happen.)
