This Air Materiel Command file, released by the U.S. Department of War, holds Incident Summary Sheets 173 through 233, sent under a 1949 transmittal. Most of the sheets record sightings of unidentified aerial objects in 1948 and early 1949. They cover Santa Fe, New Mexico, San Pablo, California, Honolulu, Kentwood, Louisiana, and Jackson, Mississippi. Each sheet gives the observer's details and the object's size, speed and shape, and often an investigator's note on how reliable the witness seemed. The file ends with a blank guide for investigating reports, including radar sightings.

While Mr. George H. Hoffman and Roy E. Statzer were approaching the city limits of Dayton, Ohio, via Siebenthaler Ave., near Stillwater Bridge, the evening of 3 Dec 48 (Approximately 1713 hours), Mr. Hoffman observed an unusual pulse of light like that of a rocket. The light appeared in the Northwest section of the sky. He estimated this pulse to be visible for about 1/2 second. After observing it for this period it flashed off. The same period of time elapsed and it reappeared seemingly in an ascendent position (could have been traveling in an easterly direction). It again remained visible for about 1/2 second when it again flashed off. It was not seen again. Mr. Hoffman thought that Mr. Statzer saw one of the pulses of light. The light appeared irregular in contour and seemed about an inch in length from the observer's viewpoint. Mr. Hoffman estimated it to be some 10 miles distant and stated that it was some 1.5° above the horizon. He thought the altitude could have been anywhere from 10,000 to 20,000 feet. The color appeared white with a yellowish tinge and was solid. There was no evidence of exhaust. The light remained constant during the 1/2 seconds observed. The part of the sky in which the light was observed appeared clear. There was no cloud interference. However, there was a layer of clouds along the horizon. There was some wind. No planet appeared to be in the air at the time. Observer states that he is mildly color-blind. Estimates his judgment of speed of moving objects as not too accurate. He believes he can distinguishe size and shape at a distance fairly well. Observer is cleared for "Secret"
