Actually 5B-DDE. The aircraft was meant to become 2-BDDE while in storage, but the paperwork took too long and the aircraft had to be reverted back to 5B-DDE. To make the reregistering easier (and because such stickers are expensive), the "5" was replaced by a piece of A4 paper with a "2" on it. By now, that piece of paper has been blown off, revealing this hybrid version of the registration. As I write this caption, I realize it's already been a year since the aircraft first touched down at Eelde. I hope it still has a future somewhere.
