I also think it would look great right side up. Would be a pity if it ended up upside down again.

Don’t see why the wings couldnt be supported by a number of thick toughened glass trestles to allow the Dornier to be displayed the right way up. Seems a shame to go to all the trouble of recovering it and then display it upside down when the cockpit and nose area (and their relationship to the shoulder wing) is probably the most distinctive part of the aircraft
