If you go to Duxford, you may also wish to include a brief visit North Weald on the way. It defended Londoon against Zeppelins and Gothas in WW1 and was a key fighter station in WW2, also hosting two of the US Eagle squadrons, as well as Norwegians, Canadians Czechs and Poles. The Battle of Britain and Band of Brothers were both partly filmed there too. A nice English tea should be available at The Squadron.
