USAF Analysis of Flying Object Incidents in the U.S., Cases 101-172

1947-1948210 pp.Confidence: HIGHhigh

This is the second of two volumes of the US Air Force study "Analysis of Flying Object Incidents in the U.S.," covering numbered Incidents 101 through 172. It uses the same method as the first volume: a standardized 26 field "CHECK-LIST - UNIDENTIFIED FLYING OBJECTS" per incident, followed by narrative remarks and, in several cases, attached correspondence and expert assessments. It continues usaf-analysis-flying-objects-1-100.md and shares its format exactly.

Key excerpts

“Remarks: Oscar Monnig, of the Texas Observers, [amateur] Astronomy [...] offers "tangible proof that th[e] fireball of February 18 over northern Kansas was just that, inasmuch as meteorites have been recovered from it." There were found, beginning April 2[..], first several small fragments [up] to one of 4 1/2 pounds. Then a disturbed spot in a clover field led to "the digging up of a piece of some 1[0]9 pounds embedded about two feet in the soil." (p. 57-69 region; Incident #101)”
“[The] astronomers of Chamberlin Observatory (Denver) did not so assess it: it is said in the dispatch that these officials could offer no explanation of it. If this is the case, the appearance is anomalous, and may lend itself to other meteoric explanation. (p. 110 region; Incident #101 supplement)”
