10,000? I have never seen that widely reported before. According to Wikipedia and other Global Sources the Russian anti-aircraft, Sam missiles and Triple A ground fire strategies used by the North Vietnamese shot down everything America put in the sky. records show hundreds of B-52s thousands of F4 Phantom jets, thousands of Huey helicopters. the Pentagon the Air Force and Army reported the complete opposite. They said US dominated the air over Vietnam. Truth is The North Vietnamese did. They only lost 2300 aircraft. But combined forces of the United States Australia Canada and other Allied Forces lost over 13,000..
I had interviewed some Aces from America. They insisted USA dominated the skies but in fact records now show in one-on-one dog fights the North Vietnamese Pilots beat American Pilots five to one…!. this is sickening makes you wonder why we ever go to war with 3rd World countries who have the will to win
