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.
