It sounds like Sir Geoge Cayley has some witness info which could have been of use to the investigators. I get miffed by poor r/t (on both sides), but have never felt sufficiently outraged or ego-strong to make a noise about it - so perhaps the FISO really did overstep the mark that day.
Did you get asked? or volunteer it?

ps. Yes - the Lydd INFO radio voice is still very controller like - I think he's trying to make the place sound a bit like, as well as look a bit like, an International Passenger Airport.
