UFO

Shell R. Alpert, a United States Coast Guard photographer at the Salem, Mass., air station photographed what appear to be unidentified flying objects flying in a "V" formation at 9:35 A.M. on July 16, 1952, through a window screen. 

CORONA, New Mexico -- They say something crashed out here in the desert.

Something weird, maybe something from another planet. Definitely something the U.S. government has never fully explained.
