I was equally unaware of a folding fin on any Boeing jet airliner.
I'm strugging to get my head around the image of folding a 720's fin to get it into the hangar. Clearly, as can be seen from the KC-135 photo, fin attachments aren't designed to be capable of supporting the weight of the fin when it's folded (hence the crane).
So I'd be fascinated to know how you move an aircraft into a hangar once the fin is folded ...
