Project
Blue Book was one of a sequences of systematic studies of unidentified flying
objects (UFOs) carried out by the United States Air Force. Started in 1952, it
was the second revival of such a study (the first two of its kind being
Projects Sign and Grudge). A termination order was given for the study in
December 1969, and all activity under its auspices stopped in January 1970.
Project
Blue Book had two goals:
- to decide if UFOs were a risk to national security, and
- to scientifically examine UFO-related data.
The
Project Blue Book Archive offers researchers free online access to over 50,000
official US Government documents relating to the UFO phenomenon. A search
engine and a range of indices are also offered to modernize access to these
documents.
