I spent a couple of years at primary school in Brize in the 70's and at lunchtimes we used to run down to the perimeter fench and watch Concorde's touch & gos. Even then, we knew it was cool. And yesterday evening, I flew an approach to 07 at White Waltham as Concorde approached 09 at LHR just over my right shoulder. We were the only aircraft in the sky that I could see. Sad to think it'll never happen again.
