As promised, i had a word with my flying club about that Skymaster. There is however good and bad news.
The good news: It is based at my flying club, so a photography session would be quite do-able, at least if it weren't for the bad news ;-)
The bad news: A couple of weeks ago it didn't quite make the perfect landing. The gear locked up, and the gear doors locked down, resulting in quite a mess. Apparently the owner isn't in much of a hurry to fix it either, so it'll be out of action for a few months yet.
The search continues ;-)
