A friend of mine, who's a corporate pilot, told me about a flight to UK with the CEO of the VERY BIG company who owns the aircraft (if I told you the name of the guy you all would know who I'm talking about). On the way back, the screeners stopped them, and confiscated (evil eyeing him and all that comes with it) a small swiss army knife from the BIG BOSS's bag...and then handed it to my friend to "keep it safe". Needless to say, my sweating friend handed it back past the nearest corner!
