A family letter described fast lights

This is a CIA information report passing along a naturalized U.S. citizen's account of a November 1955 letter from a niece in eastern Europe, describing fast-moving 'flyers' that frightened locals and drew scientific attention. Pairing strange sightings with scientific activity is exactly the kind of combination intelligence services watch. It does not prove the sightings happened; its value is that officials thought the surrounding scientific reaction might matter.
