We were on detachment at Edinburgh Field in 1971 having tanked some Lightnings there from Tengah for the 50th Anniversary of the RAAF to do flypasts at Adelaide and Melbourne.
At any of the functions/Mess/social events etc the Aussies always asked us why we called the Wg Cdr ‘Boss’.
I’d no idea, having called them Boss for at least eight years.
(Of course Rule 1 on V Force was fly with the Boss if you could, knowing he’d pinch all the best routes) !
