Obviously you've never broken, bent or blatantly disregarded a "law" in your life? How about a little bit of speeding or anything else that is "against the law".
It's nice to see the fantastic holier than thou attitudes in here. Let's look at this with a sense of perspective. Letting a known figure onto the flight deck poses stuff all risk, we're not talking here about letting any old punter onto the flight deck (though I personally don't see a problem with that myself).
It's nice to see that the professional pilots of today are so slavishly bound by rules and regulation without any regard to experience and risk management skills.
You may aswell just put a robot into the cockpit if you think that sacking someone for this was a good thing.
Breaking SOP's shouldn't be done lightly, but there are times when the rule book needs to be thrown out of the window. Idiotic "safety" rules are well up on that list.
Common sense really isn't that common anymore...............
