Fonte ..... "Spies Helped the USAF Shoot Down a Third of North Vietnam’s MiG-21s" .....On Jan. 2, 1967, around 30 U.S. Air Force F-4 Phantom fighter jets flying from Ubon in Thailand shot down a full third of North Vietnam’s MiG-21s—for a loss of just one of their own.
It was a strategic victory in an air war that had been going poorly for American forces.
And now newly-declassified documents reveal that this complex mission—Operation Bolo—couldn’t have succeeded without significant help from the signal-snooping Air Force Security Service.
