C-141 Tail Number 60177 was the last of the 285 C-141's built by Lockheed to leave active service. She flew 100 POWs out of Hanoi on 12 February 1973, some of them tasting freedom for the first time in six years. Each POW put their shot-down date on the face of the oxygen panel during their flight to Clark Air Base in the Philippines . For her retirement ceremony, some of the POWs she brought home were brought back for the ceremony and one last flight by this gracious lady. Most of them are old men now but their enthusiasm, emotions, and excitement were evident during this flight and retirement ceremony. She was then flown to Dayton , Ohio where she will spend her final days in the Air Force Museum .
