Launch crew member Tom Erb walks to the launch pad area of rocket builder Steve Eves' one-tenth scale Saturn V rocket in Price, Md., on April 25, 2009. The 36-foot-high rocket, which was a three-year project costing approximately $25,000-$30,000 to build, is the largest model rocket ever successfully launched. Eves' rocket commemorates the 40th anniversary of the July 16, 1969 launch of the United States Apollo 11, which put the first man on the moon.
