Project Blue Book Special Report (second copy)

This is Project Blue Book Special Report No. 14, "Analysis of Reports of Unidentified Aerial Objects," Project No. 10073, dated 5 May 1955. The study reduced about 4,000 sighting reports received by the U.S. Air Force between June 1947 and December 1952 to IBM punched cards and analyzed them statistically, including chi square tests comparing knowns with unknowns. It concludes that the reports very probably do not represent technological developments beyond present scientific knowledge, and it notes that no case produced physical evidence.

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.
