"I hope you forgot your camera !!!"... oh yes!
I'd heard the Red Arrows would be there but I'd forgotten about it. I didn't find out about Concorde till someone said this morning "don't forget, 12:20, Concorde". They were quite low, about 1500-2000 ft, I'd guess. I went outside at 12:15 and at 12:22 there they were, Concorde leading with the Red Arrows sweeping back from it's wingtips.
