Blue StarShip/UFO Report, November 23, 2012 [1]

1952 - Salem, Massachusetts. July 16, 1952. During the peak of the 1952 UFO Flap, Shel Alpert, a USCG seaman on duty in the Coast Guard Weather Office at the Salem Coast Guard Station, saw four brilliant lights in the sky.

He called another Guardsman to see the lights, but in those few seconds the lights had become more dim. When they brightened again, he quickly took a single photograph through the window of the office.

This photo has been published in many books, newspapers and magazines. An excellent piece of evidence.
