I loved the programme, it was awesome.
I love the F-35, it's a stunning jet. My only complaint is they have not shown anything relating to Typhoon training - there are two frontline jets in the RAF, showing only one is biased.
As for calling an instructor "mate," consider that the holds are so long, there's simply no such thing as a Fg Off turning up to Valley, anymore. They're all Flt Lts/Lts and the majority of the pilots instructing at Valley, are themselves, Flt Lts/Lts, so from a seniority point of view, they're on the same level...
