Three crashes early in his career led Navy officials to question or fault his judgment.
John McCain was training in his AD-6 Skyraider on an overcast Texas morning in 1960 when he slammed into Corpus Christi Bay and sheared the skin off his plane's wings.
McCain recounted the accident decades later in his autobiography. "The engine quit while I was practicing landings," he wrote. But an investigation board at the Naval Aviation Safety Center found no evidence of engine failure.
The crash was one of three early in McCain's aviation career in which his flying skills and judgment were faulted or questioned by Navy officials.
In his most serious lapse, McCain was "clowning" around in a Skyraider over southern Spain about December 1961 and flew into electrical wires
After McCain was sent to Vietnam, his plane was destroyed in an explosion on the deck of an aircraft carrier in 1967.
