Passenger DC-10 many years ago pushing back from gate and cabin crew start the brief with the usual welcome aboard "flight XYZ to Timbuktu". But we're not going to Timbuktu shout most of the passengers in unison, we're going to Sin City. Answer - well your all on the wrong aircraft you should be on the one to our left (same aircraft type, which was likewise pushing back). Brakes on, five minutes of sorting to find all is in order and on we go. Always wondered what might have been the cause.
Must confess to Miles, did the same, long, long flight line, wrong aircraft and flew the mission.
