Overhead view of the Missile Gallery at the National Museum of the U.S. Air Force. Opened to the public in 2004, the Missile Gallery is contained in a silo-like structure that stands 140 feet high. Visitors can view missiles such as the Titan I and II and Jupiter from ground level or can take in an aerial view from an elevated platform that hugs the inside circumference of the gallery.(U.S. Air Force photo by Ty Greenlees)
