The Space Shuttle Discovery's first launch was on August 30, 1984. Having completed 39 successful mission, this spacecraft has flown more than any other, including the flight that launched the Hubble Space Telescope. Discovery's last flight was made on March 9, 2011. The shuttle now rests at the Smithsonian Museum in Washington, D.C. The Metal Earth Models easily pop out of their frame. Put them together and then show them off! Tweezers make an ideal tool for bending or twisting the connection tabs. Instructions are included in each package. For ages 14 and up. The steel models make for great gifts for those who love working with models. They make perfect decor and centerpieces on your table or shelf that your friends will love admiring.
