Not exactly related to your question, but I had the unique oportunity to spend a few hours in the Do-728 prototype D-AEVA that the DLR (German Aerospace Center) bought. It's in a small building at the DLR in Göttingen, and it's in quite good condition. They use it for experiments on cabin climate and I earned some money participating in an early calibration test using the original aircraft systems before they will install new experimental systems. The aircraft still carries Dornier colors and is in quite a good condition. It has Lufthansa seats fitted throughout the cabin. I have only a few crappy exterior pics I took with my mobile phone, here are two of them:

(Large pics, about 700kb. The building is too small to go further away, so a fisheye would be needed to get a picture of the whole aircraft.)
