There is so much evidence on the existence of UFOs and, subsequently, ETs, that it defies common sense that everyone does not know about them. The
only explanation for this non-dissemination of knowledge is the successful information blocking expertise of those who do not want the public to know.
I want the public to know.
The Many Types of ufo evidence
1. Public Eyewitness accounts: Millions of people have seen strange objects in the sky that did not behave like anything they have ever seen before.
Hundreds of thousands of these people have given reports of their sightings to their government authorities.
2. Historical and Artistic Records: There are thousands of historical or artistic records of phenomena that fit the description of current day UFOs
and ETs. See the encyclopedic works of Jerome Clark, the four volume set "U.F.O.s and Extraterrestrials in History" by Yves Naud, or a graduate
thesis of UFOs in History as shown thru art by the Italian woman, Stefania Genovese.
3. Aircraft Pilot Sightings: Over ten thousand aircraft pilots have seen UFOs during day and night. Ex-NASA scientist, Richard Haines, has recorded
over 3,500 aircraft pilots’ sightings of UFOs. These pilots have seen UFOs up close, which means within a mile. Some of these pilots have slowly
steered their planes or jets to get closer to the UFOs, which would only allow them to get so close. Other pilots have actually chased them, but the
UFOs have always eluded them. When the UFOs approached the aircraft too closely, many of the planes instruments went haywire.
3b. Military Aircraft Activities: There have been hundreds of air force pilots that have tried to attack UFOs and some have fired machine gun blasts,
canons, and air to air missiles at them. According to second hand statements by a handful of military people, some pilots were destroyed by trying to
attack. However, most pilots had their weapons systems neutralized or their avionics shutdown. They also had their radar jammed and had the tables
turned on them.
4. Radar and Visual Sightings: There have been thousands of radar and visual sightings of UFOs. These simultaneous viewings have been recorded since
the 1940’s. The July 1952 sightings over Washington D.C. had up to three different radar stations tracking the same visually sighted UFO.
5. Radioactivity, Radar and Visual Sightings: There have been simultaneous visual, radar and radioactivity recordings of UFOs. The first USAF director
of Project Bluebook publicly documented this. See Edward Ruppelt’s “The Report on Unidentified Flying Objects” Chapter 15.
6. Photographic and Video Evidence: Hundreds of thousands of photographs, films and videos have been taken of UFOs and yet very little of this ever
gets put in newspapers or TV news programs. Many of the few photos that did make the newspapers were the rare hoaxes or the easily explained
misperceptions of the public. Many of the early photographs and films were either stolen or confiscated by the military or intelligence personnel.
7. Transportation Vehicles Effected: Gasoline-powered cars have stalled when a UFO approached too closely. This has happened in hundreds of recorded
instances. At the same time, nearby diesel engines were not affected. In addition, the car’s lights, windshield wipers, cigarette lighter and
anything in the car that required electricity from the battery was made inoperable when the UFO was in the near vicinity of the vehicle.
8. Communication Devices Effected: Thousands of TVs, radios, and cell phones have failed to work properly when a UFO was too close.
9. Scientific Measurements: Magnetic, electrostatic and electromagnetic measurements have been taken when UFOs were in the vicinity of the measuring
equipment.
10. Landing Traces: UFOs have landed and left imprints on the ground. In addition, torn, bent and charred vegetation, soil and rocks have been
analyzed and found to have many strange electromagnetic and biological characteristics that are not naturally found at the landing site. Vegetation
will not grow and seeds will not germinate for extended periods of time. At some UFO landing sites, the soil has been dehydrated and will not absorb
water.
11. Strange Animal Behavior: There are thousands of cases where animals have behaved strangely when a UFO is spotted nearby. Some horses and cattle
will run around wildly. Some dogs and pets will hide. Some animals will not move in the direction of the UFO.
13. Crop Circles: Thousands of crop circles have occurred over hundreds of years. Some of these circles are incredibly detailed. Yet, the only
explanation that was acknowledged in the media was of two old beer-drinking men, one of whom is now dead, confessed to making “most” of them. I
guess the ghost of the ex-crop hoaxer is the busiest ghost in history. Laboratory analysis has shown chemical changes and strange magnetic anomalies
to the bent plants and surrounding soil in many crop circles that could not be caused if a prankster was bending the plant thru mechanical means.
14. Human Implants: Thousands of implants have been recovered. Of those analyzed, none appear to be of any known material on Earth that is either
naturally occurring or man-made. Typically, laboratory analysis shows that the isotopes of the elements in the implant are not common or even known on
the Earth’s surface.
15. Human Abductions: Thousands of people claim to have been abducted. The writings of Budd Hopkins, David Jacobs, John E. Mack, and James Harder have
shown the experiences in detail of hundreds of people who have been abducted.
16. Human Impregnations: Thousands of women claim to have been impregnated and had their fetuses removed generally by the third month. These women and
their doctors are perplexed by the changes in their once pregnant bodies.
17. Astronaut Sightings: Astronauts and cosmonauts have stated publicly that they have seen UFOs. Astronauts, scientists and technicians have stated
that they have seen and photographed UFOs on and near the moon, and artificial structures on the Moon and Mars.
18. Law Enforcement Sightings: Thousands of policemen have reported UFO sightings and many have been harassed for doing so. Dozens of law enforcement
officials and technical personnel have lost their jobs and more when they came forth with testimony regarding UFOs.
