A few from inside.
Unfortunately there is a bit of wasted space inside where they could put one or more of the rarer types, but I believe they have other aircraft that they rotate with those on show, as a photo on one of the displays that was taken about 10 years ago has quite a few aircraft on the deck that are no longer there, with the current ones in their place.
As I found with quite a few of the museums in the USA, although the aircraft on display are excellent, as are the museums, they tend to be a bit dark, making photographing difficult. (My apologies for a couple of these being a touch fuzzy).
