First the facts: Joe Biden twice told the story of his uncle Ambrose, who volunteered during World War II and was lost at sea when his airplane crashed for unknown reasons into the ocean new New Guinea. New Guinea at the time did indeed have cannibal tribes.
Do these facts match up with Biden's tale? You be the judge.
So, "Uncle Bosey" did indeed exist and he did crash his airplane in the general region of New Guinea, although it was offshore. The plane was not single-engine (so what? Even I wouldn't remember the type of plane after decades), and one out of the four on the plane was recovered.
Nobody shot down the airplane. The engines failed for some reason.
Brian Krassenstein, a Biden shill, tried to save his butt by claiming the story was factual, but even his rewriting of the facts makes Biden out to be a fabulist.
