I liked seeing the clip with Cunningham in the context of Trident Autoland testing, for which he was the dH (later HS) Test Pilot.
On both that and in the testing of the Comet autopilot, both made by Smiths (of course
), one of the Smiths' avionics Flight Test Engineers was the co-founder and, when I joined, still the gaffer of our Staverton syndicate. He was a PPL, builder/restorer, and PFA Inspector. For some Comet flights he sat in the P2 seat, and had Cunningham (name and signature) as P1 in his PPL logbook
When we lived in Switzerland, '50s-'60s, our flights between Geneva and London were usually BEA (old livery, of course) Viscounts, Vanguards, Comet 4B or Trident. When we first moved there, Swissair were using Convair Metropolitans on the route, but eventually introduced Caravelles. I recall the BEA cabin staff with refined British accents in English, still audible in their excellent French also
