Analysis — our summary

William Hoffmeyer of Jackson, Minnesota, wrote to the FBI reporting that his uncle found a round pile of shredded tinfoil-like material in a pasture, beneath which the clover appeared burned. Three similar burned patches in a triangular arrangement were observed. A neighbor's wife reported seeing a steady white light circling the farm the previous Sunday night. The FBI forwarded Hoffmeyer's letter and the physical sample to Air Force intelligence; no further analysis results are recorded in this file.
