This document is about the creation of Project Sign, the forerunner of Project Grudge and later on the well known Project Blue Book. Air Force
headquarters in Washington send this classified document to the Air Force command of Wright Patterson AFB in a response of a earlier report/request
from this AFB into the regards of unidentified flying objects. Is worth noting that at the beginning the government and the military had the tendency
of informing the American public about the phenomena and their origin, if they were friendly or hostile. (As we all know this attitude later was to
change).
In the report is stated that till the moment this document was created they were 180 cases identified and investigated by the Air Force classifying
them in four groups:
1. Flat disc of circular or approximately circular
2. Torpedo or cigar shaped aircrafts with no wings or fins visible in flight
3. Spherical or balloon shaped objects
4. Balls of light with no apparent form attached
After this the document goes on explaining some of the cases investigated by Air Force pinpointing that the possibility that this flying objects are
of non terrestrial origin has been taken in consideration. The documents concludes that at the moment no results or conclusions were meet due to the
unknown nature of the phenomena and the lack of more detailed datas.
Short document and not very clear to go through but interesting nonetheless.
