Project Blue Book: Air Force UFO Study

PROJECT BLUE BOOK

Duration: 1952-1969

Cases Investigated: 12,618

Unexplained: 701 (5.6%)

CONCLUSION:

"No UFO reported, investigated, and evaluated

by the Air Force was ever an indication of threat

to our national security."

But Dr. J. Allen Hynek (scientific advisor) later said:

"Blue Book was a cover-up."

What happened to the 701 unexplained cases?

Where did they go?

The investigation "ended" but the phenomenon didn't.
