Retired Air Force Col. Robert Certain, a B-52 navigator and former prisoner of war, worked with MOAA to organize a trip back to Vietnam to commemorate the 50th anniversary of Operation Homecoming and the return of more than 600 POWs from North Vietnam. Seven former POWs as well as family and friends joined Certain to see southern Vietnam and Cambodia and return to Hanoi to see what remains of the infamous Hanoi Hilton prison.
