Not trying to hijack your thread but "Talking Pictures TV" showed the 1952 film "The Sound Barrier" a couple of days ago. In my opinion that was an excellent interpretation of our industry at a time when several of its founding fathers were still around and in positions of responsibility.
A bit of suspension of disbelief was necessary to cope with the de Havilland Comet erecting shop at Hatfield standing in for Ridgefields and the heroine finding "JR" himself listening to the R/T of the fatal flight in Bill Mallon's office. JR's proper office was our Service Department by the time I knew it.
Since the Supermarine 535 which stood in for the Prometheus was not a Hatfield aeroplane, the aerodrome sequences were shot elsewhere.
