June 2 is World UFO Day, when people are invited to get together and watch the skies for unidentified flying objects.
In the past there were two World UFO days: July 2 and June 24, before the WUFODO (World UFO Day Organization) declared July 2 to be the official day to watch for alien spacecraft.
June 24 is the date that aviator Kenneth Arnold reported what is generally considered to be the first sighting of an unidentified flying object in the United States, while July 2 commemorates the supposed UFO crash in the 1947 Roswell UFO incident.
The Roswell UFO incident took place in the USA in 1947, when an airborne object crashed on a ranch near Roswell, New Mexico, on July. Explanations of what actually took place are based on both official and unofficial communications. The most popular theory of what happened is that the object was a spacecraft containing extraterrestrial life. Since the late 1970s, the Roswell incident has been the subject of much controversy, and conspiracy theories have arisen about the event.
The United States Armed Forces maintains that what was recovered near Roswell was debris from the crash of an experimental high-altitude surveillance balloon belonging to what was then a classified (top secret) program named Mogul. In contrast, many UFO proponents maintain that an alien craft was found, its occupants were captured, and that the military engaged in a massive cover-up. The Roswell incident has turned into a widely known pop culture phenomenon, making the name “Roswell” synonymous with UFOs. Roswell has become the most publicized and controversial of all alleged UFO incidents.
On July 8, 1947, the Roswell Army Air Field (RAAF) public information officer Walter Haut in Roswell, New Mexico, issued a press release stating that personnel from the field’s 509th Operations Group had recovered a “flying disk”, which had crashed on a ranch near Roswell.
Later that day, the press reported that Commanding General of the Eighth Air Force Roger Ramey had stated that a weather balloon was recovered by the RAAF personnel. A press conference was held, featuring debris (foil, rubber and wood) said to be from the crashed object, which seemed to confirm its description as a weather balloon.
Subsequently the incident was forgotten and almost completely ignored, even by UFO researchers, for more than 30 years. In 1978, physicist and ufologist Stanton T. Friedman interviewed Major Jesse Marcel who was involved with the original recovery of the debris in 1947. Marcel expressed his belief that the military covered up the recovery of an alien spacecraft. His story spread through UFO circles, being featured in some UFO documentaries at the time.
In February 1980, the National Enquirer ran its own interview with Marcel, garnering national and worldwide attention for the Roswell incident. Additional witnesses added significant new details, including claims of a huge military operation dedicated to recovering alien craft and aliens themselves, at as many as 11 crash sites, and alleged witness intimidation. In 1989, former mortician Glenn Dennis put forth a detailed personal account, wherein he claimed alien autopsies were carried out at the Roswell base.
