Special Report No. 14 was issued by the U.S. Air Force's Air Technical Intelligence Center on 5 May 1955. It is a statistical study of about 4,000 reports of unidentified aerial objects from June 1947 to December 1952. The reports were reduced to IBM punched cards and analyzed with methods including chi square tests. The report concludes that the reports it examined are very unlikely to represent technology beyond present scientific knowledge, and it notes that no case produced valid physical evidence.

I
A pilot and copilot were flying a DC-3 at 0340 hours on July 24, 1948,
when they saw an object coming toward them. It passed to the right and
slightly above them, at which time it went into a ste^p climb and was lost
from sight in some clouds. Duration of the observation was about 10
seqonds. One passenger was able to catch a flash of light as the object
passed. The object seemed powered by rocket or jet motors shooting a
trail of fire some 50 feet to the rear of the object. The object had no wings
or other protrusion and had two rows of lighted windows.
