that's something that an idiot will only do once, and after that he may not have any fingers left to do it again.
It's been a common sight to see RC models burst into flame after hitting the deck, and thankfully I haven't had one go up after I've connected with terra firma, but it's quite possible that if you deck an electric C/L model you may have a fire on your hands, even hours after you've gone home.
Treat any decked, bent, mangled or puffed pack with suspicion, and like Andrew said, discharge them out of the house, until they are dead.
