As far as "best of 2014" lists go, the CIA has a pretty irresistible one: On Dec. 22 it started tweeting links to the 10 most popular articles of the year that it shared on Twitter, and the agency arrived at No. 1 yesterday, tweeting: "Reports of unusual activity in the skies in the '50s? It was us." The accompanying link directs readers to The CIA and the U-2 Program, 1954-1974, a 272-page document from 1998 the CIA tweeted a link to in early July, reported KAKE at the time.
The upshot of the report is that the CIA was the culprit behind more than half of the UFO sightings logged in the 1950s and 1960s.
