Documents / FOIA release
This CIA-released copy of Project Blue Book Special Report No. 14 is dated 5 May 1955 and comes from the Air Technical Intelligence Center at Wright-Patterson Air Force Base. It is a statistical analysis of about 4,000 unidentified aerial object reports from 1947 through 1952, coded onto IBM punched cards with the help of a panel of scientists. The report concludes that such objects were highly unlikely to be technological developments beyond present-day scientific knowledge. It also found no valid evidence of physical matter.
Case VIII (Serial 0576.00) An electrician was standing by the bathroom window of his home, facing west, at 0825 hours on July 31, 1948, when he first sighted an object. He ran to his kitchen where he pointed out the object to his wife. Total time in sight was approximately 10 seconds, during which the object flew on a straight and level course from horizon to horizon, west to east. (Ratio approx. 3:1)
