I went to Duxford, and we too flew in. I think it was a great day. It's easy to poke holes in the procedures but on the whole, I think the staff were plainly working hard to look after everyone and it certainly didn't spoil our day.
As for the comment about the French commentator, I will happily listen to any nationality if the speaker is clear, knowledgeable and enthusiastic - and he was.
I'll be back next year.
