Helpful Stacker - thanks for the explanation
Thread drift away from aviation from a minute - we were once queueing outside St Paul's Cathedral for admittance to Good Friday evensong. I remarked to Mrs TTN that they would be letting us in in good time for the service, and an Australian tourist in front of us turned and asked "Is this a church then?" On receiving an affirmative reply he shouldered his backpack and ambled off!
