The attractive thing about Duxford was it was also a well-developed national museum, with all the facilities, plus the huge interest in the hangars, the American museum, etc, which enabled the whole family to make a day of it. Sywell may try hard but doesn't really come up to that.
I suppose the only hope is that the proposed new ideas for Duxford don't live up to it financially (quite possible), the new whizz-bang know-nothing management are embarrassed, and get replaced.
