The Pulsing Light over Montevideo
One night in late March 1955 a CIA source and his wife watched an intensely bright light hover over Montevideo with a smaller light beneath it, then glide south pulsing four seconds bright and one second dim, while people watched from the street and their windows. He told the Agency he was certain it was no conventional aircraft or missile. This is the record of what he reported, not a verdict on what was over the city.
