Beags,
I was one such backend Nimrod Kapitan and I agree with you...it was nonsense. It was also trivial, as everybody knew what their jobs were and got on with them, be that Tac Nav, P1, Lead Dry, lead wet whatever.
See good crews and good aircrew understood the name of the game was to be a team...and by large 95% of kipper fleet were very very good at being a team.
Of course, all fleets had their dodgy 5% (you know, the guys who could not quite cut it), but on Nimrods, these chaps, whatever their brevet, would not have got the captaincy gig.
Which is why your story - as oft repeated as it is - is bollocks.
PS not saying it didn't happen - it probably happened a thousand times...but not from the captain...from every other outspoken ****er on the crew. And if the pilot bit...more fool him.
PPS
All yours then, Captain!", he announced and went to make himself a coffee
That bolded bit alone gives the game away.
