Violent encounter in Florida

This article details a reported encounter in the Florida Everglades on the night of March 14-15, 1965, involving a man named Mr. James Flynn. While exercising his hunting dogs, Flynn observed a brightly-lit, cone-shaped object approximately three stories in height. He reported hearing a loud buzzing noise. As he approached the object, he was struck by what he described as a 'sledgehammer blow' to the forehead, which rendered him unconscious. Upon regaining consciousness the following day, he found himself partially blind and eventually navigated to an Indian reservation for medical assistance. Medical examination revealed a bloodshot eye and evidence of a heavy blow. The article notes that while some suggested he may have walked into a tree branch, a follow-up letter from Mrs. Helen G. Hartmann of the St. Petersburg U.F.O. Research Organization reported that a burned ring, 70 to 75 feet in diameter, was discovered at the site, with eight trees mashed or felled. The author compares this incident to a previous report by Horace Burns regarding a similar object in Virginia and discusses the possibility that the witness was affected by a force-field associated with the craft.
