Former Vietnam prisoners of war line up to board the Hanoi Taxi, a C-141 U.S. Air Force aircraft, for a 79-minute flight at Wright-Patterson Air Force Base, Friday, May 5, 2006, in Dayton, Ohio. More than 30 years later, the Air Force is retiring the aircraft that in two trips rescued 79 POWs captured during the Vietnam War. Many of those who took the flights of freedom reunited Friday to ride the Hanoi Taxi once more and relive the unforgettable. (AP Photo)
