Several UFO stories appeared in the news this week, many miles and years apart. Yet they share a possible similar explanation: Earth-based remote-controlled devices.
Earlier this month, the FBI created a new website, "The Vault," which offers the public an opportunity to view documents in an online "electronic reading room."
Some of the 2,000-plus documents are about UFOs, including several from 1947 -- right around the time of the famously reported UFO crash near Roswell, N.M.
