A FOIA request resulted in the declassification of 1,500 pages of UFO-related research not long ago. It cited 42 examples in which individuals were injured as a result of purported contacts with “anomalous vehicles,” or UFOs, as they were exposed to electromagnetic radiation, some of which were reportedly caused by “energy-related propulsion systems.”

More than 1,500 pages of UFO-related information from the Advanced Aerospace Threat Identification Program (AATIP) — a clandestine US Department of Defense program that operated from 2007 to 2012 — are included in the database of papers. However, it turns out that the detrimental effects of UFOs on individuals are nothing new. Historians are looking into a 350-year-old UFO case that is still a mystery. The event occurred at 2 p.m. on April 8, 1665, when a group of fisherman moored near Barhofft observed what they described as “ships in the sky” fighting.

“After a time, a flat, round figure rose from the sky, like a plate or a giant man’s hat,” wrote author Erasmus Francis, who compiled news accounts of the event in 1689. “It was the hue of a lowering moon, and it hung directly above St. Nicholas Church.” Until the evening, the flying object remained immobile. The fisherman, who were overjoyed, covered their faces with their hands to avoid looking at this scene.” According to Francisca’s story, many who saw the things quickly fell unwell, shaking and experiencing agony in their heads and limbs.

The whole thing was eventually deemed “inexplicable,” and the reason of the men’s illnesses was never discovered. Researchers Chris Obeck and Martin Shaw looked at numerous plausible reasons for what the fishermen were seeing in their June 2015 examination, but were unable to come up with a definite solution. They eventually concluded that this was a UFO sighting, albeit it is unclear if it was one of the earliest in history.
