Yes, we know this museum is closer to Tucson than Phoenix, but the bottom line is that the Titan Missile Museum is the only missile site in the nation that the public can actually visit. So if you think in terms of the entire country, this missile museum is right in our backyard. And this place is like nowhere else in the Valley: It's a complex of steel-reinforced concrete, completely underground, with three-ton blast doors and a 103-foot Titan II missile. The missile silo, which was operational starting in 1963, was one of more than 32 Titan II silos throughout the country. The missile in Green Valley was de-activated in 1982 (along with the rest of the Titan IIs), but this is the only silo that survived demolition. And the museum still sees a lot of action — many scenes from the 1996 film Star Trek: First Contact were shot there, and the public can tour the facility. Tours include restored engines, the control room, and a simulated launch. There are even overnight stays in the crew facilities for more adventurous tourists.
