Flying Saucers Over DC?

In the 1950s, Washington seems to have been a popular destination for UFOs, both actual ones and cinematic. Two popular science fiction movies, 1951'sThe Day the Earth Stood Still and 1956's Earth Vs the Flying Saucersdepicted alien spacecraft arriving in the nation's capital, to the consternation of both residents and the government. But those close encounters may have seemed a bit more plausible, given that the Washington area also was the scene of one of the most celebrated real-life UFO incidents ever--one that still intrigues those who ponder the possiblity of extraterrestrial visits to Earth.
