As a naval aviator, McCain flew attack aircraft from carriers. During the Vietnam War, he narrowly escaped death in the 1967 "Forrestal" fire. On his twenty-third bombing mission during Operation Rolling Thunder in October 1967, he was shot down over Hanoi and badly injured. He subsequently endured five and a half years as a prisoner of war, including periods of torture. In 1968, he refused a North Vietnamese offer of early release, because it would have meant leaving before other prisoners who had been held longer. He was released in 1973 after the Paris Peace Accords.
