Sure, why would they lie?
Stop it…
It is funny how project bluebook quietly ended after the Soviets were finally able to shoot down that pesky UFO violating their airspace… imagine their surprise after all our denials, that it was our U2 spy plane. Was probably an awkward conversation later at the embassy…
“On December 17, 1969, the Secretary of the Air Force announced the termination of Project BLUE BOOK, the Air Force program for the investigation of UFOS.
From 1947 to 1969, a total of 12, 618 sightings were reported to Project BLUE BOOK. Of these 701 remain "Unidentified." The project was headquartered at Wright-Patterson Air Force Base, whose personnel no longer receive, document or investigate UFO reports.”

“An international diplomatic crisis erupted in May 1960 when the Union of Soviet Socialist Republics (USSR) shot down an American U-2 spy plane in Soviet air space and captured its pilot, Francis Gary Powers (1929-77). Confronted with the evidence of his nation’s espionage, President Dwight D. Eisenhower (1890-1969) was forced to admit to the Soviets that the U.S. Central Intelligence Agency (CIA) had been flying spy missions over the USSR for several years.”
