You simply must fly to DAY and go to the Air Force Museum at Wright-Patt. There you can walk around/under/whatever almost every warplane you can think of. My favorites: B-36, XB-70, SR-71, YF-22, F-117, B-52... You can also walk through several of the old Air Force Ones, including the 707.
Speaking of the Revel B-36 model: My father built that model for me when I was very young. He did a very professional job with it and it hung from my ceiling for years. It was huge! When I was arount twelve or thirteen I was really into, um, burning things and blowing stuff up. That great old model became a test bed for explosives -- namely, black-cats. After I finished blowing the plane to bits, I set it on fire. There is still an airplane-shaped silhouette on my mom's back patio where the plastic melted and left a toxic sludge. Gosh, I really wish I still had that model! Sadly, many of my GI Joes met the same fate in the match-stick towers of death I built for them.
