If you have a few more hours to spare, the Cradle of Aviation Museum is a do-not-miss. It's up in Long Island next to the the now defunct Roosevelt Field (is a shopping mall
). If you are into anything built by Grumman - including the LEM then it's a real treasure trove. A lot of the curators are ex-Grumman employees and worked on the exhibits during their R&D and construction phase.
