News.com reporter Daniel Terdiman visited the Titan Missile Museum in Sahuarita, Ariz., as part of his Road Trip 2007 around the Southwest.
Located about 20 miles south of Tucson, the museum is located on a former Titan missile launching site. There, crews of four worked 24-hour shifts during which two people always had to be together to ensure safety and security. In this image, the tip of the missile--with warhead removed--is viewed from above through a glass window that allows museum visitors to peer down into the silo.
