In 1960 he crashed into Corpus Christi Bay claiming his engine quit.
But an investigation board at the Naval Aviation Safety Center found no evidence of engine failure.
The 23-year-old junior lieutenant wasn't paying attention and erred in using "a power setting too low to maintain level flight in a turn," investigators concluded.
In 1961 McCain's plane hit power lines in Spain causing a blackout.
In his most serious lapse, McCain was "clowning" around in a Skyraider over southern Spain about December 1961 and flew into electrical wires, causing a blackout, according to McCain's own account as well as those of naval officers and enlistees aboard the carrier Intrepid.
Nowadays the Navy wouldn't allow someone with his questionable judgment to fly a multi-million dollar aircraft so I guess it's only fitting that he could be running the country come January.
