It's a very interesting museum which I visited a few years ago. Whereas the larger museums seem to focus on military and WW2 hardware the Anchorage museum naturally exhibits the lighter side of aviation. It's probably not large enough to warrant a long trip, even for an aviation enthusiast such as I was, but if you are in the area don't miss it. Of course, after spending an hour or so there spend some more time a few minutes walk from there watching the action on Lake Hood.

The other (unidentified) "modern" airplane is an early model Boeing 737; a 100 series I would say. The photo of the unidentified "primitive" biplane is familiar but I can't remember what the type is.
