All of this stuff is brilliant until you find yourself on the green (or white) bits found an the sides of the black stuff. Then, you tell the humourless man in the blue uniform that you were properly briefed because you decoded the runway state message using your iPhone. When standing in court a few days later, the nice man in the blue uniform reads out what you said - at this point in the proceedings all of your former colleagues quietly slide out of the room, never to be seen again.
