4. Churchill Covers Up RAF/UFO Encounter To "Avoid Mass Panic"

Winston Churchill feared public panic and a widespread loss of faith in religion when he covered up an encounter between an RAF bomber and a UFO during the second World War. That's according to a trove of declassified documents on UFO sightings released in 2010 by the National Archives. General Dwight Eisenhower was present when Churchill gave the order to cover up the encounter, forbidding information about it from being released for fifty years.

The encounter took place between a a reconnaissance plane and a metallic-looking UFO which shadowed them. At the time, earthly origins for the UFC (such as it being a missile) were ruled out. There's no telling how many more encounters like this took place, as UFO records prior to 1967 were routinely destroyed.
