The sightings of Washington, DC, 1952
Reports of U.F.O’s sparked the founding of The Robertson Panel of the C.I.A. Not only were there several reports of mysterious objects floating above Washington, there were odd changes in radar signals at 3 different airports. There were very real fears of an oncoming invasion of aliens, however, the U.S. Air Force attempted to calm the storm by suggesting that changes in temperature were to blame for the odd radar signals.
Everyone has a damn good camera with them at all times and noone has seen an UFO for years.
