There are two surviving Yorks; at Cosford and Duxford. The one at IWM Duxford is ex-Dan Air G-ANTK that saw RAF service as MW232 from 1946 and flew on the Berlin Airlift. It now belongs to the Duxford Aviation Society along with 11 other airliners including Ambassador G-ALZO and Comet 4 G-APYD, both also ex-Dan Air.
There are moves afoot to redevelop the part of Duxford that the DAS flight line occupies to WWII appearance. That means that the flight line, together with the DAS workshops and offices, would be on the move. Hopefully that would be elsewhere at Duxford, but these are early days.
