I don't think that we've had rockets blow up on the pad and do a bunch of damage, but once they're up and out, I don't think we ever, in the US anyway, had that problem because we always had the ability to blow it up. If it's, there's red lines, and if it passes a red line, you push the button. Now it's all done autonomously. So you have gps monitors on board that self destruct. If it sees that it's going past the line, there's nobody with the button anymore. It's all automatic.
