They contained the history of planes, and all their whereabouts. The reason I disliked them was that some of the information was highly sophisticated, and only an expert on planes could interpret the information. The moon rock one can touch. Focuses on historical development. Nonetheless, the most modern exhibits are very recent and the educational displays reasonably so.
Most displays hold the attention and get their point over.
My wife liked it a lot. Males and females liked it equally. All the exhibits are real artifacts, accurate, informative, and inspiring. The collection is very extensive. I have seen the national science and technology museums in Ottawa and London, and the U.S. National Air and Space Museum is the best.
