A Boy Scout waves from the cockpit of an Air Force Reserve KC-135 Stratotanker, while other scouts and their families wait to tour the jet Sept. 29, 2007 at Beale Air Force Base, Calif. The jet, which is owned by the 940th Air Refueling Wing at Beale, was only one of many displays the 7,000 scouts saw during the Boy Scout Expo at the base Sept. 28-30.
