America's first UFO

OXCART was declassified in 1994. Some forgotten hero at the AP cross-referenced the available logs of U2 flights, A12 flights and SR-71 flights with all the officially unexplained sightings in Project Blue Book and claimed that every single one of them was a CIA test flight.

This is the way mythos works - when the CIA itself claimed that everything unexplained in PBB was a U2 in 2015, "experts" go

"One thing this CIA UFO claim has accomplished: It has united UFO skeptics and proponents in proclaiming it untrue," Robert Sheaffer, author and well-known UFO cynic, wrote in a blog post last week. "We might agree on little else, except that this claim is nonsense."

Sheaffer explains that the Project Blue Book files are now public records, allowing anyone to verify when and where sightings were reported.

"The bottom line is: There is absolutely no correlation between the times and places of UFO reports and U-2 flights," he wrote.

Because fundamentally

Some witnesses to the Bug’s crash described seeing a pilot parachute out of the drone, or described its descent as the actions of a drunk or crazy pilot. But the Army did not dispute those perceptions—instead it went so far as to say the nonexistent pilot had jumped out early and was receiving treatment in a hospital. The witnesses who led the Army to its missing drone were not trusted with the honest truth of what they had seen, as a matter of national security.
