Blaming the Forrestal accident on McCain is a stretch, as it was his plane that was hit by a misfired missile from another aircraft on the flight deck, not the other way around. However, there is a version of events that lays at least some of the blame on McCain.
BUSH LIKELY BLACKMAILING McCAIN OVER DEADLY NAVAL ACCIDENTS
However, I have heard folks who flew with him over Vietnam say that he was one of the worst pilots ever and would have been grounded except for who his father was. In addition they mostly say he wasn't shot down but suffered a "controlled flight into terrain" accident.
LOL. If the President is "blackmailing" McCain, he is not doing a very good job of it. (How many of these loonies are out there?)
Interesting information -thanks.
