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 VI (Serial 4822.00)
An instrument technician, while driving from a large city toward an
Air Force base on December. 22, 1952, saw an object from his car at 1930
hours. He stopped his car to' watch it. It suddenly moved up toward the
zenith in spurts from right to left at an angle of about 45°. It then moved
off in level flight at a high rate of speed, during which maneuver it appeared
white most of the time, but apparently rolled three times showing a red
side. About halfway through its roll it showed no light at all. It finally
assumed a position to the south of the planet Jupiter at a high altitude, at
which position it darted back and forth, left and right alternately. Total
time of the observation was 15 minutes. Apparently, the observer just
stopped watching the object.
No light
