for the newfags:
In June of 1947, over Mount Rainier, Washington, Pilot Kenneth Arnold reported spotting objects that he described as circular in shape flying in formation at an unfathomable high rate of speed. Following an Air Force investigation, Pilot Arnold’s report was dismissed as inaccurate. Kenneth Arnold died in 1984 and always stood by his story, maintaining it was his duty to report such an incident.
