At the risk of pre-empting HD, Years ago an inbound to Heathrow on downwind (was it a Trident or 1-11? Mike Romeo suggests a 1-11) was 'forgotten' by the director, sailed off for miles and miles in the wrong direction, and subsequent to that it always got a priority service into Heathrow because ATC felt sorry for it! I even hear that clever crews who had heard the story used to falsely claim they were MR!
