For aerospace nuts 1-day isn't even enough, much too much to see and do and the variety of aircraft is amazing. The walking tour is a must, it's only an hour or so. Our guide was a pilot who previously flew off the USS Shangra La, his stories and insights were facinating. Also make sure to chat up the volunteers at the various exhibits. Many were pilots or had some association with the exhibits and are more than happy to share the history and wondorful stories!
