Documents / FOIA release
This FBI file section collects July 1947 Bureau memoranda, teletypes, citizen letters and newspaper clippings about reported flying discs. They cover recovered objects at Twin Falls, Idaho, Shreveport, Louisiana, Black River Falls, Wisconsin, and Laurel, Maryland, many judged to be pranks, plus a Grafton, Wisconsin priest's circular saw blade the Milwaukee office called a hoax. A Dallas teletype reports a disc recovered near Roswell resembling a high altitude weather balloon with radar reflector. Kenneth Arnold's own account of his sighting is also included.

New Jersey residents said they "thought" they saw flying disks over Palisades Park and near-by Bergenfield Sunday night. Skeptical scientists recalled the mysterious "rockets" seen over Sweden last year. Eighty per cent of the "ghost rockets" proved to be meteors, and Swedish officials said the others could be discounted as pure imagination. Scientists asserted that the objects in order to be seen clearly at 10,000 feet—the level at which most of the saucers have been reported would have to be 20 feet in diameter, would require a large mass of metal, would be more conspicuous at night and would be seen by a far greater number of persons. Dr. J. S. Nassau, director of the Warner & Swasey observatory at the Case Institute of Technology at Cleveland, said he was inclined to "think the reports are fancies." Capt. Tom Brown, army air force spokesman at Washington, said the army was trying to run the reports to Earth. "We're not dismissing the possibility that there's something to it," he said, "and we're not dismissing the possibility that it's all a hoax."
