you DO NOT want to be around transformers when they explode, bad deal... they are filled with oil that is typically VERY hot and can easily cause 3rd degree burns
just yesterday i responded to an MVA (motor vehicle accident) a car had slide off the highway (not sure how, it wasnt raining or anything) and flipped, the person was wearing a seatbelt but the car was on fire so we had to get our brush truck with foam to put it out, the danger with car fires is the possibility of explosions later on and you cant use water on oil fires, anyway just wanted to share my experience
i think its best you didnt put yourself into the situation, if you would have been around when the transformer blew that would not have been a good ending for you, sadly it was a bad ending for the 3...
glad your alright though
