The episode argues that the 1947 Roswell incident was merely the most famous of numerous UFO crash retrievals conducted by world governments in the late 1940s, with wreckage allegedly stored at secret military installations including Area 51 in Nevada, Kapustin Yar in Russia, Pine Gap in Australia, and Rudloe Manor in England. Ancient astronaut theorists point to a 1950 FBI memo to J. Edgar Hoover describing three recovered "flying saucers" in New Mexico as evidence that the initial military report of a captured flying disc was accurate before being changed to the weather balloon explanation. Richard Dolan, Linda Moulton Howe, and Giorgio Tsoukalos contend that governments have been reverse-engineering extraterrestrial technology from these crashes for decades, with Tsoukalos visiting the original Walker Air Force Base hangar where alien bodies were purportedly stored.
Mainstream historians note that the FBI memo cited informant reports rather than confirmed evidence, and that the military's Project Mogul—a classified high-altitude balloon program monitoring Soviet nuclear tests—offers a documented explanation for unusual debris that would have required secrecy in 1947. The "weather balloon" cover story was technically inaccurate but served to protect genuinely classified Cold War surveillance technology. Skeptics point out that witness accounts of alien bodies emerged decades after the event, not contemporaneously. Still, the episode compellingly documents how many official documents about Roswell remain classified, and why a nuclear-capable military base misidentifying debris has fueled seventy years of questions about what transparency the public deserves regarding unidentified aerial phenomena.
Braxton County, West Virginia (UFO crash site)
United States · Modern
Theorists cite Braxton County, West Virginia as one of several American locations with reported mysterious crashes around the time of Roswell, suggesting a wider pattern of extraterrestrial activity. The 'Flatwoods Monster' incident of September 1952 in Braxton County is a well-known UFO case in popular literature, though officially unexplained.
Cape Girardeau, Missouri (1941 crash site)
United States · Modern
Theorists argue that on April 12, 1941, a disc-shaped craft carrying extraterrestrial beings crashed near Cape Girardeau, Missouri, and was attended by Reverend William Huffman who was sworn to secrecy by the military; they call it 'The Bombshell Before Roswell' and claim it established the military's retrieval and cover-up protocols. No mainstream archaeological or governmental confirmation of this event exists; the account derives from deathbed testimony relayed by Huffman's family decades later.
Hebgen Lake, Montana (UFO crash site)
United States · Modern
Theorists list Hebgen Lake, Montana as one of multiple American crash sites reported around the time of Roswell, supporting the claim of a broader pattern of extraterrestrial incidents. No mainstream confirmation of an extraterrestrial crash at this location has been provided.
Kapustin Yar
Russia · Modern
Kapustin Yar is rumored to be a secret military base where wreckage from UFO crashes reported around the time of Roswell was retrieved and hidden away.
Lund University, Sweden (Element 115 confirmation)
Sweden · Modern
Theorists argue that the confirmation of Element 115 (ununpentium) by researchers at Lund University in 2013 validates whistleblower Bob Lazar's decades-old claim that extraterrestrial craft at Area 51 were powered by this element, which he said did not exist naturally on Earth. Mainstream scientists describe ununpentium as a synthetic superheavy element created through nuclear fusion in a laboratory, with no known connection to extraterrestrial technology.
Pine Gap
Australia · Modern
Pine Gap is rumored to be a secret military base where wreckage from UFO crashes reported around the time of Roswell was retrieved and hidden away.
Remote runways / test site, China (hills of China)
China · Modern
Theorists claim that a series of bizarre runways over a mile long and a half-mile wide in the remote hills of China, where strange aircraft have been spotted, serve as a testing ground for extraterrestrial spacecraft. No mainstream identification of the specific site or confirmation of extraterrestrial activity has been provided in the episode.
Roswell
United States · Modern (1947)
1947 crash of an alien spacecraft covered up by the US military
Rudloe Manor
England · Modern
Rudloe Manor appears to be a standard English manor house but researchers argue it has been the epicenter of British research into UFOs since World War II and may contain hidden UFO artifacts.
San Antonio, New Mexico (UFO crash site)
United States · Modern
Theorists cite San Antonio, New Mexico as one of several American locations where mysterious crashes were reported around the same time as Roswell, suggesting a wider pattern of extraterrestrial incidents. No mainstream scientific or governmental confirmation of an extraterrestrial crash at this location exists.
Twin Falls, Idaho (UFO crash site)
United States · Modern
Theorists list Twin Falls, Idaho as one of multiple American crash sites reported around the time of Roswell, supporting the claim of a broader pattern of extraterrestrial incidents. No mainstream confirmation of an extraterrestrial crash at this location has been provided.
