bushb... That's you back on the dole then...
Some may recall the days of the Civil Aviation Flying Unit.. and some of the chaps flying for it who thought they were someone special. One of them barked at a Glasgow controller one day: "What's the QNH" to which the reply given was: "It's the subscale setting on an altimeter such that the altimeter reads height above sea level on the surface of the airfield".
They don't make 'em like that nowadays.
