John McCain’s grandfather, a four-star admiral and one of the navy’s greatest commanders, led the strongest aircraft carrier force of the Third Fleet during World War II. McCain’s father, also a four-star admiral, served as commander of all U.S. forces in the Pacific during the Vietnam War. It was in Vietnam that John McCain III faced the most difficult challenge of his life. A naval aviator, he was shot down over Hanoi in 1967. Recognized as the son of a top commander, McCain was tortured and imprisoned for five and a half years. Despite this, he refused Vietnamese offers of an early release. What McCain learned from his grandfather and father enabled him to survive those hard years.
