Mistaken ranks?
Many moons ago, on a Shackleton Deployment to Keflavic, one of the mission crew (who had imbibed a few drinks) introduced the Flt Lt Shackleton captain as the Detatchment Commander Shackleton Atlantic - or should I say that he abbreviated this title to "Det Com Shack Lant". The result was a quick beeline of American SOs who wished to meet such a distinguished guest.
