What was reported

A 208-page scanned box of individual 'CHECK-LIST - UNIDENTIFIED FLYING OBJECTS' case files, Incidents #1 through roughly #100, each a single Army Air Forces/Air Materiel Command investigation form (witness data, distance, altitude, speed, shape, color, sound, remarks) plus attached correspondence. Incident #1 is dated 8 July 1947, two weeks after the Kenneth Arnold sighting and in the same window as the Roswell announcement; incidents sampled run through January and October 1948. Sampled cases include military witnesses (control-tower personnel at Muroc and Clinton County AAF), civilians, and press reports relayed through military attaches abroad (Finland). Most describe fireballs, lights, or disc/triangle-shaped objects with no instrument corroboration.

Why this rating Single untrained witness, visual-only observation in nearly every sampled case; no radar or photographic corroboration seen in the sampled pages. Several cases sampled are plausibly fireballs/meteors or, in one case, an admitted rocket explosion; others (the Clinton County AAF two-witness sighting, the Plevna letter) are more detailed but still single-sensor (the naked eye) even with more than one observer.
