Maybe it's a bit of a lads place to visit, but having said that I went with my 2 daughters and they loved it as well. Overall we saw the ship, a submarine from the inside, the space shuttle, and many other very cool place including the sr 71 spy plane. They also have a numb of good simulators which the kids live of course. They make me feel ill, but that's just me. Was funny to see my daughter crashing assimilation over and over and hang upside down laughing. As museums go its. Very digestible, about three hours and you will see it all well. Also got e chance to sit Ina few relics and even a space pod.
No need to go back but very worthwhile
