McCain graduated from the Naval Academy in 1958, ranked 894th out of 899. As historians have noted, there were five people in his class who were actually bigger fuckups than McCain, but none of them are running for president.
McCain, commissioned an ensign, spent two and a half years training as a naval aviator in Pensacola. There he earned a reputation as a party man, drove a Corvette, dated an exotic dancer named "Marie the Flame of Florida," and, as he would later say, "generally misused my good health and youth." But at least when it came to flying, he took his responsibilities seriously.
Just kidding. He didn't care about those either -- he was a below average flyer, and couldn't be bothered to read his aviation manuals. But, as many noted partying experts have asked, what good could possibly come of reading manuals? It's not like one might have a situation in which one's plane would quit while landing and crash into Corpus Christi Bay, or be flying too low in Spain and take out some power lines, or crash while en route to Philadelphia for an Army/Navy football game.
