Air Force Sightings of UFOs

Between 19 forty eight and 19 69, the air force investigated 12 thousand 618 reported u f o sightings. The project grudge was a kind of separate project where they were going through and essentially trying to debunk the findings of project sign or just to explain all of them away. And then in 19 53, it kind of had its third little iteration, which became a thing that you'd probably have heard of, and we've talked about before on the show, called project blue book.
