Many years ago, as an ATCO at LATCC, in the early hours in the morning, the only aircraft on frequency was a Lufthansa 747. As he came up to Woodley he changed course slightly. Just to show that I was watching him I said LHxxx, I see you have just made a course correction, are you OK ? He replied: Sorry London I should have advised you. Just trying to give my passengers a better view of London. My reply Confirm you are LH oder Luftwaffe. Happy days.
