Awesome, I did Biggin Hill back in the early 1990s, well worth it. Have a great day, and I hope the weather holds out for you.
Had two warbirds go over earlier, couldn't get a decent look at them but I think they might have been Mustangs, one had D-day stripes so it was probably the two that were at Bentwaters the other week, they might well have been bound for Biggin.
