UAPs: Objects Discovered Same Day UFOs Flew Over D.C. in 1952 with Beatriz Villarroel

John Michael Godier's Event Horizon

Not of this Earth? On the night of July 19th, 1952 something rather strange happened on two fronts in North America. At that time, one of the most puzzling UFO flaps in history was happening in the Washington, DC area including multiple radar returns and visual sightings from people in several locations. At Mount Palomar observatory in Southern California, a pair of photographic plates were taken about one hour apart, one just before 9 pm, the other just before 10 pm local time. In these plates, one showed a cluster of three star-like points, essentially indistinguishable from stars. But in the second plate, the points had abruptly and inexplicably disappeared.
