JET CHASE OFL LARGE CIRCULAR
OBJECT INVESTIGATED
BY FAR EAST AIR FORCE
For eight months the Far East Air Force has s been in possession of an Intelligence Report
describing the jet chase of a strange round object larger than a B-29 bomber. According
to this report, the UFO accelerated to a speed of abo miles per hour when the jet
tried to close in.
Intelligence Report Details Released to NICAP
Full details of the chase were revealed to NICAP on August 29 in an unclassified Full details of the chase were revealed to NICAP on August 29 in an unclassified
section of the Intelligence Report. This is the first detailed report of a jet-UFO chase section of the Intelligence Report. This is the st detailed report of a jet-UFO chase
released anywhere in the Air Force since 1953. Whether release of this important case released anywhere in t ir Force since 1953. Whether release of this important case
