The following is a very good and highly recommended documentary on the UFO subject. The documentary goes through the history of the phenomenon and explains very well that a certain percentage of UFOs are indeed extraterrestrial and that the U.S. government and military has acted to cover-up the phenomenon. Included below are special features with additional interviews.
This YouTube version of the documentary is edited. I would recommend viewers see the unedited version of the documentary on Netflix. The unedited version of the documentary contains most of the following which is not contained in the edited YouTube version below:
-Interviews with Budd Hopkins & Dr. David Jacobs on alien abductions, the creation of hybrid beings, and the future takeover of the planet.
-Linda Moulton Howe - Cattle mutilations and how she was tricked by Richard Doty.
-Why the MJ-12 Papers are fake - They have connections to Richard Doty.
-Why the U.S.A.F. Rosewell explanation is created by the same people who likely created the MJ-12 Papers.
- Crop Circles
- Betty & Barney Hill
- The origin of the 'swamp gas' psuedoexplanation for UFOs.
