I'm afraid that I wasn't very impressed with this programme. The business of Army/RN resentment at the "absence" of the RAF at Dunkirk was dealt with in the Battle of Britain film, so this was hardly breaking new ground despite all the "astonishing things" mentioned.
BTW, I seem to remember in the film Lawrence Olivier (as Dowding) saying that he had lost 400 aircraft in and over France, whereas this programme spoke of 900 I think. Were the other 500 not from Fighter Command?
As to the discussion of Officer v NCO pay, the old F6663 was a constant reminder of such discrepancies. With a crew of many Master Aircrew, as well as Flt Sgts and Sgts, mostly married, as a single Flg Off aircraft captain I was often drawing less pay than my co-pilot, navigator, flight-engineer, signaller, or loadmaster. As always with the Service, you were paid for the rank, not the job, with or without marriage allowance.
