Nobody tortured John McCain, the Fortunate Son, in Vietnam. They didn't have to.
Once they found out who he was he was given kid-glove treatment.
Nhan Dan published answers to questions by one of its correspondents made by a U.S. air pirate detained in North Vietnam. "He is Lt. John Sidney McCain . . ."

"To a question of the correspondent, McCain answered: 'My assignment to the Oriskany, I told myself, was due to serious losses in pilots which were sustained by this aircraft carrier due to its raids over North Vietnam territory and which necessitated replacements. From 10 to 12 pilots were transferred like me from the Forrestal to the Oriskany . . . upon arrival near the target, our formation, with six bombers, would mount the attack according to the following order: I would be number three, and the chief of the formation, number one. Each pilot would have to approach the target from a different direction, the choice of which would be left to him.'"
