This video has been disputed by others who were in the same POW camp, and by American doctors who worked on his injuries after his release – but for sake of argument, lets look only at the undisputed facts prior to his capture.
As Trump was enjoying the Ivy League and avoiding the war, McCain was about to become one of its most high-profile casualties.
Lieutenant commander McCain had been flying for months, conducting targeted strikes on North Vietnam. He had already been injured in an aircraft carrier fire that killed 134 fellow sailors. (and no he did not cause the explosion as another anti-McCain bogus youtube suggest). And he had already made a name for himself as a pilot.
On Oct. 25, 1967, McCain had destroyed two enemy MiG fighter planes parked on a runway outside Hanoi.
He was on his 23rd mission, flying right over the heart of Hanoi in a dive at about 4,500 feet, when a Russian missile the size of a telephone pole came up and blew the right wing off his Skyhawk which went inverted in almost straight-down spin. He pulled the ejection handle, and was knocked unconscious by the force of the ejection.”
McCain regained consciousness when his parachute landed him in a lake. The explosion had shattered both arms and one of his legs. With 50 pounds of gear on him and one good limb, he struggled to swim to the surface. North Vietnamese dragged him to shore. Then stripped him to his underwear and began “hollering and screaming and cursing and spitting and kicking him.
In my book McCain is a Hero even if he was picked up immediately by a rescue helicopter. But I'm a "Trump hater", so you can discount everything I wrote above, I don't really care, because Your Trump is not going to win the nomination anyway.
