Astra : correct. Flytdeck ; endearing. Recalling heady days of bombing into LHR in the tripot, an ATCO had an immediately distinguishable "Sarf Landon" accent and in response to our "Good Morning" would reply "Maunin" ! I was never held to book when leaving a frequency, as instructed, with a "Cheers mate.............nice one !" ! Aaaaah, but that was in the good ole days.
