At present the Wroughton collection is a collection of unrestored aircraft housed in hangars of which only one is accessable. Moving them to Duxford would not only make them all accessable and viewable, but also ensure they are restored and maintained. The DC-3 at Wroughton is a case in point. This particular aircraft is, I believe, one of the oldest survivors of its type and was the fifth aircraft delivered to United Airlines.
Together with the "Friends of the DC-3", an offer was made to fully restore this aircraft and repaint it in its original United Airlines colours, without any charge to the Science Museum whatsoever, other than the cost of the paint. They wouldn't even fund that!!! Their excuse was ' it's present livery is part of its history and that's how we want to keep it'.
I believe due to corrosion in the tail wheel mounting, this aircraft can't be moved anyway...so much for 'preservation'.
