Always enjoyed listening to the Amsterdam approach controllers on a rough day, as they manoevered everyone round buildups etc - impressively cool to listen to - probably a bit more stressful for the guy doing it.
Was listening the day after Raymond van Barneveld won the world title - a slightly startled sounding Northwest flight was cleared onto heading 'one hundred and eighhhhhhhhhhhhhhty'. 'err, say again?'. Don't think the pilot was a darts afficianado!
