Hah! Yeah, well, Apollo 12 got hit by lightning twice after launching in a bad rainstorm. They blew out some power supply or something which screwed up all their telemetry and a bunch of other stuff. Fun way to begin your badass rocket trip, seventeen alarms and lights going off all at once!

Fortunately they could switch to a backup, and everything went back to normal after that.
Astronauts are some damn freaky people. Or well, the extreme opposite of that I really should say. Ice cool level-headed unflappable guys. A normal person would panic or shut down in such a situation, they monitor and analyze, then correct. Amazing.
Sad to see the launch not happening today, btw. It would have been so epic. Alas, such is the way of things, it's not really a disappointment. It's just how we have to do things, bad things tend to happen when one starts to skimp on safety. History has taught us that many times, and not just when it comes to space flight.
