And yet the US Secret Service took care of that too! How do you film a UFO that suddenly appears in front of you? 
As the X-Files reported, the truth is out there somewhere, or in this case it could be hiding somewhere in the 130,000 formerly classified documents from USAF (United States Air Force) UFO investigations conducted between 1947 and 1969.
Using the Freedom of Information Act and after filing over 5,000 requests covering almost everything from the Kennedy assassination to CIA experiments, John Greenwald Jr. managed to amass 130,000 pages of classified documents.
One of the strangest comes from the 1960s and includes an educational guide describing how to take better photos of UFOs.
So, if you want to record a UFO, the CIA recommends:
