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.

Case X (Serial 1119.00)
An employee in the supersonic laboratory of an aeronautical lab-
oratory and some other employees of this lab, were by a river, 2-1/2
miles from its mouth, when they saw an object. The time was about 1700
hours on May 24, 1949. The object was reflecting sunlight when observed
by naked eye. However, he then looked at it with 8-power binoculars, at
which time there was no glare. (Did glasses have filter?) It was of
metallic construction and was seen with good enough resolution to show
that the skin was dirty. It moved off in horizontal flight at a gradually in-
creasing rate of speed, until it seemed to approach the speed of a jet
before it disappeared. No propulsion was apparent. Time of observation
was 2-l/2 to 3 minutes.
