USAF Analysis of Flying Object Incidents in the U.S., Cases 1-100

1947-1948253 pp.Confidence: HIGHhigh

This is the first of two volumes of a US Air Force study, "Analysis of Flying Object Incidents in the U.S.," covering numbered Incidents 1 through 100 from the 1947 to 1948 wave. The method is a standardized one page "CHECK-LIST - UNIDENTIFIED FLYING OBJECTS" per incident, recording 26 fixed data fields, followed by a narrative remarks section. It is a primary case catalog, not a policy paper, and it is continued in usaf-analysis-flying-objects-101-172.md.

Key excerpts

“Incident occurred just before break of day. Object appeared to [Mrs] Brimberry as a large round ball of fire about 26 to 30 inches in diameter with a "tail" of approximately 20 feet in length. This "tail" seemed to diminish as it approached the ground. It appeared to have suddenly "gone out" just before it reached the earth. [...] Mr Brimberry described the object as being "almost round, maybe a little oval or saucer-shaped and giving off a bright light. It appeared to be spinning. (p. 7229 region; Incident #98)”
“The Fairfield Control Tower obtained a report at approximately 2300 EST 30 Dec 47 from Hamilton Fld Flight Control, that a motorist on U. S. Highway #40, 30 miles west of Lovelock, Nevada [...] had seen an object explode in the air at a height of 1200 to 1300 feet. (p. 7122 region; Incident #96)”
