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.
