Kenneth Arnold sits inside Bureau intake

This is a 1947 FBI headquarters file gathering dozens of summer 1947 'flying disc' reports from field offices and witnesses, including a Fourth Air Force investigation with Kenneth Arnold's own account, plus the Maury Island hoax and FBI-Army liaison memos. A historically important sighting and a notorious hoax sit right next to each other here. That is the useful warning: serious reports and pure noise traveled through the very same official channels.
