Someone I know who overflies NK every once in a while says that he makes sure to give Mr. Kim the finger at least once while in their airspace.
Excellent, I always used to do a similar thing every time I flew over France. Always went for a wee (sometimes a number two) and flushed. I know, I know it doesn't come out of the aircraft but it always made me smile. Wonder what my fellow passengers used to think when I came out of the can with a silly grin on my face.
