Orson Welles in the 'Mutiny on the Bounty'?
He acted in a radio version in 1939 - did you really hear that, PN? Or did you mean Charles Laughton in the role of Capt Bligh in the 1935 version?
One thing the V-force did have right was the "First, Co, Rad, Plot, AEO" crew response on intercomm. And if things were serious, then "Captain to Crew" raised the level of attention appropriately! Much easier than the truckie force where the U/T captain is called 'Captain' even if he/she isn't, with the real Captain, the QFI, sitting in the co-pilot's seat!
