This is what happens when you have the camera setup to take that shot and all of a sudden BANG. You could hear the whole sky crackle, you could feel it, then a massive instant kaboom that just about blew me off the veranda with my wife and 2 daughters letting out a petrified yell/scream. Funny now but at the time it was massive and scared the hell out of me. It blew 2 transformers and we lost power till almost 3:00 am.
