A couple of years ago, 'Erindoors ventured on one of Mr O'Leary's machines. It took off from Stockholm, more or less on time and came in to land a few minutes early. Usual announcement; "Ladies and gentlemen, we have landed at Stansted, please remain in your seats... " etc, etc.
Mrs Beak rose to get her stuff together, looked out of the window, and called the nearest flight attendant over. "If we've just landed at Stansted, why does it say Groningen on that building over there?"
The poor girl looked out, looked flustered, blinked, then said, "Actually, I don't know where we are," then vanished up the sharp end.
After twenty minutes the machine took off, and went to Stansted as planned. No announcement, no apology, no nothing.
Fuel stop? Pilot picking up a friend? Mistook? Weird.
