The British UFO Files Documentary
Focusing on the UFO phenomena as it occurred in Britain, this documentary examines a large set of files that had been released by the UK government. Files that had previously been labeled as Top Secret, this release of information covers the UK government's investigations into UFOs going back to WWII times, when pilots had submitted eyewitness accounts of objects that they worried were Nazi creations. The UK government was so serious about the threat -- internationally or interplanetary -- that Churchill himself showed interest in the topic. Of course, the video then goes into detail about how the UK government suppressed and hid the testimonies and evidences of these encounters, often using the same tactics as their US counterparts.
