I believe the first time you posted this, the point was raised that the image does not show enough female body parts :-))) Seriously though, I understand this photo does indeed have a limited audience, as the average viewer without an interest in the history of flying will probably not be able to appreciate the subject.
I would be interested in the technical details of this shot, if you still have them recorded somewhere. Shooting in museum lighting conditions can be quite difficult, but you got the exposure right on target with this shot, so I am curious to know how you did it.
