Unexplained UFO files

1. 1947 Roswell crash: UFO proponents claimed that the US military had captured a crashed alien aircraft. This well-publicised, controversial incident became apop culture phenomenon.
Explanation: the US military maintained that it had recovered debris from an experimental high-altitude surveillance balloon belonging to a classified programme named “Mogul”.
2. 1947 Kenneth Arnold case: the press coined the term “flying saucer” after this American businessman and pilot claimed he had seen nine objects flying in achain near Mount Rainier, Washington. Arnold described them as saucers skipping across water.Explanation: The US Air Force formally listed the caseas a mirage.
3. 1952 Washington, D.C. flap: this series of UFO reports was accompanied by radar contacts at three separate airports. Country-wide headlines spurred the formation of the CIA Robertson Panel.
Explanation: the US Air Force suggested that a temperature inversion - in which a layer of warm, moist air covered a layer of cool, dry air closer to the ground - had caused radar signals to bend and give false returns.
4. 1957 Levelland case: police investigated numerous motorist reports of engines stalling when encountering a glowing, egg-shaped object. Motorists claimed that their vehicles had restarted after the "object" had left.
Explanation: an air force investigation concluded thatan electrical storm had caused the sightings and vehicle failures.
5. 1966 Westall encounter: more than 200 students and teachers at two schools in Melbourne allegedly saw a UFO that descended into a grass field. The object then ascended over a local suburb, according to reports. Witnesses still gather for reunions.Explanation: Australian Skeptics, a non-profit organisation which investigates paranormal and pseudo-scientific claims by using scientific methodologies, believed that the object was an experimental military aircraft.
6. 1967 Shag Harbour crash: a large object crashed into Shag Harbour, Nova Scotia.
Explanation: The Canadian Department of National Defence officially classified this sighting as unsolved following a naval search and investigation. The Condon Committee, which investigated UFOs at the University of Colorado, failed to resolve the case.
7. 1976 Tehran incident: A UFO was believed to have disabled the electronic equipment of two F-4 interceptor aircraft as well as ground control equipment. The Iranian generals involved said on public record that they had thought the object was extraterrestrial.
Explanation:UFOs: The Public Deceived, a book by Philip Klass, claimed that witnesses saw an astronomical body - probably Jupiter - and pilot incompetence and equipment malfunction accountedfor the rest.
8. 1986 São Paulo chase: around 20 UFOs were seen and detected by radar in various parts of Brazil. They reportedly disappeared as five military aircraft were sent to intercept them.
Explanation: Geoffrey Perry, a British space researcher, attributed the incident to debris that were ejected by Soviet space station Salyut-7 and re-entered Earth’s atmosphere around central-western Brazil.
9. 1989/1990 Belgium wave: around 13,500 people claimed to have witnessed large, silent, low-flying black triangles. Around 2,600 filed written statements describing what they had seen. The frequently-photographed wave was tracked by NATO radar and jet interceptors and investigated by Belgium’s military.
Explanation: Renaud Leclet, a French ufologist, believed some of the sightings could have been explained by helicopters.
10. 2008 Turkey video: a night guard at the Yeni Kent Compound claimed he had video taped multiple UFOs

Aliens, the mystery continues

Deep Universe

Aliens and Area 51 : Its secretive nature and undoubted connection to classified aircraft research, together with reports of unusual phenomena, have led Area 51 to become a focus of modern UFO and conspiracy theories. Some of the activities mentioned in such theories at Area 51 include:

The storage, examination, and reverse engineering of crashed alien spacecraft (including material supposedly recovered at Roswell), the study of their occupants (living and dead), and the manufacture of aircraft based on alien technology.
Meetings or joint undertakings with extraterrestrials.
The development of exotic energy weapons for the Strategic Defense Initiative (SDI) or other weapons programs.
The development of means of weather control.
The development of time travel and teleportation technology.
The development of unusual and exotic propulsion systems related to the Aurora Program.
Activities related to a supposed shadowy one world government or the Majestic 12 organization.
Many of the hypotheses concern underground facilities at Groom or at Papoose Lake (also known as "S-4 location"), 8.5 miles (13.7 km) south, and include claims of a transcontinental underground railroad system, a disappearing airstrip (nicknamed the "Cheshire Airstrip", after Lewis Carroll's Cheshire cat) which briefly appears when water is sprayed onto its camouflaged asphalt, and engineering based on alien technology. Publicly available satellite imagery, however, reveals clearly visible landing strips at Groom Dry Lake, but not at Papoose Lake.

In the mid-1950s, civilian aircraft flew under 20,000 feet while military aircraft flew under 40,000 feet. Once the U-2 began flying at above 60,000 feet, an unexpected side effect was an increasing number of UFO sighting reports. Sightings occurred most often during early evenings hours, when airline pilots flying west saw the U-2's silver wings reflect the setting sun, giving the aircraft a "fiery" appearance. Many sighting reports came to the Air Force's Project Blue Book, which investigated UFO sightings, through air-traffic controllers and letters to the government. The project checked U-2 and later OXCART flight records to eliminate the majority of UFO reports it received during the late 1950s and 1960s, although it could not reveal to the letter writers the truth behind what they saw.[25]:72–73 Similarly, veterans of experimental projects such as OXCART and NERVA at Area 51 agree that their work (including 2,850 OXCART test flights alone) inadvertently prompted many of the UFO sightings and other rumors:

The shape of OXCART was unprecedented, with its wide, disk-like fuselage designed to carry vast quantities of fuel. Commercial pilots cruising over Nevada at dusk would look up and see the bottom of OXCART whiz by at 2,000-plus mph. The aircraft's titanium body, moving as fast as a bullet, would reflect the sun's rays in a way that could make anyone think, UFO.

They believe that the rumors helped maintain secrecy over Area 51's actual operations. While the veterans deny the existence of a vast underground railroad system, many of Area 51's operations did (and presumably still do) occur underground.

Bob Lazar
See: S-4 (facility) for further information
Several people have claimed knowledge of events supporting Area 51 conspiracy theories. These have included Bob Lazar, who claimed in 1989 that he had worked at Area 51's "Sector Four (S-4)", said to be located underground inside the Papoose Range near Papoose Lake. Lazar has stated he was contracted to work with alien spacecraft that the U.S. government had in its possession.
Bruce Burgess
Similarly, the 1996 documentary Dreamland directed by Bruce Burgess included an interview with a 71-year-old mechanical engineer who claimed to be a former employee at Area 51 during the 1950s. His claims included that he had worked on a "flying disc simulator" which had been based on a disc originating from a crashed extraterrestrial craft and was used to train US Pilots. He also claimed to have worked with an extraterrestrial being named "J-Rod" and described as a "telepathic translator".
Dan Burisch
In 2004, Dan Burisch (pseudonym of Dan Crain) claimed to have worked on cloning alien viruses at Area 51, also alongside the alien named "J-Rod". Burisch's scholarly credentials are the subject of much debate, as he was apparently working as a Las Vegas parole officer in 1989 while also earning a PhD at State University of New York (SUNY).
