I found the old-plane portion of the Musee de l'Air et de l'Espace in Paris to be the most interesting part. It is in the old Booking Hall. The newest aircraft in that portion of the museum is an all-metal Junkers from 1919.
I see from their Web site that part of that Hall may be temporarily closed.
This museum is a worthy complement to Old Warden for the oldest aircraft. The info cards were in English as well as French the last time I was there.
