Read the caption again from the Library of Congress...Captured not rescued.
Don't mince words with me...
After the SAM struck McCain's plane he was spiraling violently toward earth at over 500 miles per hour. He managed to pull the ejection seat handle blowing him out of his disabled aircraft. He struck part of the plane, breaking his left arm, his right arm in three places, and his right knee. He landed in the middle of a lake in the center of the city. He pulled the life vest toggle with his teeth. In a matter of seconds hundreds of Vietnamese were beating him. Someone smashed a rifle butt into his shoulder, breaking it. Another jabbed him in the ankle and the groin with a bayonet. Fortunately an army truck arrived and he was thrown in the back and taken away from the savage mob. For sure he would have been killed in another minute or so.
If you about to be killed (in one minute or so), you are rescued even if it is into hell. Not like he was gonna walk out of there on his own.. there was not much an underground railroad to rely on was there.
I understand where you are coming from, but I asked a question and didn't expect to be grilled over something so trivial as "rescued or captured" especially when both are relevant.
