It's really tragic in cases like these when you never know when something like this is likely to happen.
I've had this happen to me a couple of times, and the last time was on my way home from a monthly check with my LBS! I changed gear going into Old Street Roundabout and the chain popped off. I fell on my handlebars and kind of spreadeagled on top of it and luckily my feet hitthe ground first. I looekd a like a complete idiot in the middle of the roudnabout but it could have been worse.
For a few months after this I never stood up on pedals! At least if you are sitting down you have less chance of falling off
