There's a lot of nonsense spoken by individuals about the alleged snobbishness at BOAC.
During a visit to England in the early 1980's I met Captain David Beaty who wrote a book on flight safety called The Naked Pilot. David was a former wartime bomber pilot who joined BOAC after leaving the RAF. He also wrote a book called Call me Captain,based upon his time in BOAC. I stand to be corrected as it was a long time ago. He lived in Sussex or Kent then. At the time I was a 737 captain with a South Pacific operator as well as being a former RAAF pilot.
David kindly invited my wife and I into his cottage for a cuppa and chat. I mentioned how much I had enjoyed his book. The Naked Pilot was all about pilot error incidents and accidents. David said he had experienced great reluctance by many of the captains he had interviewed for his book, to admit they had made mistakes.
I suggested to him that if he ever got around to writing a sequel to The Naked Pilot, it would be worthwhile his interviewing airline first officers as they would have been immediate witnesses to their captain's mistakes.
I must have inadvertently crossed a line in the sand of British Class, because as soon as I suggested First Officers as a source of information, David rose to his feet, thanked me curtly for my time and gave my wife and I the metaphorical bum's rush out of the door. We drove away, shaking our heads in bewilderment.
