Excellent! Did not expect much prior to visiting, as this visit was researched and planned by someone else because we had to be on Long Island for a wedding weekend. Having designed products for flight, I thought this was just going to be another airplane museum with a few planes in a hangar type situation. I was wrong. Definitely did not allocate enough time (2 hours) to enjoy all the exhibits. There were four scheduled movies that day in the planetarium dome theater, and we did not pay extra to view them, and the titles did not indicate they were strictly aviation topics; so I can't comment on that. We went on Mother's Day, and it was not crowded. The building exterior was nothing special, which is fine because the insides were very special. We first went to the Jet gallery, to see the A-6F, cockpit of a Boeing 707, A-10, and F-14A. I thought this was how the whole museum was going to be -- nice presentations with some write-ups, but the main galleries were amazing. I suggest you ask to find the correct place to start to go in chronological order, because we did not, and wish we had. We randomly went up the staircase and had some amazing views of the entrance lobby and galleries below, and hanging vehicles of all shapes and sizes. Once down on the main floor, the experience was interesting and educational, all types of exhibits, some just for viewing, and some interactive. There were local historical displays, some relevant to Grumman, and other early aviation groups, training schools, and events. Information on aircraft construction and flight theory through the early years, and then going into progress during WWI/WWII, including weapons. Lots of full aircraft and some cutaway displays explaining advances through the years. Great displays related to aircraft carriers, and a nice little display regarding current drones. Also displays on space race, including Gemini/Apollo/Space Shuttle, and a full size Lunar Excursion Module (LEM) display!
