Take the biggest umbrella, longest windbreak and tallest stepladder you can find, and make sure you padlock everything to the fence by 08:00 so you’re tooled up for the flying in the afternoon.
And don’t forget if you go to Duxford, the sun (if any) will be in your face all the time so you’ll neeed to open up at least 2 stops! Otherwise it’ll be pouring with rain, which is where the umbrella comes in handy.
