Area 51 ranks among the world's most conspiracy-fuelled locations.
The Nevada facility's extreme secrecy has generated countless theories about alien research and UFO activity over the decades.
Built in 1955, Area 51 managed to stay off the public radar until 1989. That's when Robert Lazar made claims on TV that he'd worked there studying extra-terrestrial technology and spacecraft.
Whether Lazar's assertions were true or not, they cemented Area 51's reputation as ground zero for government secrets related to alien life.

Now, UFO enthusiasts are claiming a government cover-up is underway following a mysterious crash at Area 51 that triggered a military investigation.
The incident occurred on 23 September when an unidentified aircraft crashed on public land just outside the classified government facility at Groom Lake, Nevada.
Creech Air Force Base confirmed early on that the crash resulted from a mishap involving an aircraft assigned to the installation's 432nd Wing, a unit that operates unmanned aerial vehicles (UAVs), commonly known as drones.
That explanation should have been the end of the story, but it wasn't.
The Air Force Office of Special Investigations and the FBI launched a joint probe into the incident, issuing a temporary flight restriction covering a five-mile stretch to the east of Area 51 'for national security reasons' on the day of the crash. This led UFO fans to slam the new measures as 'absolutely bogus' and indicative of a cover-up.
Any further details about the incident have remained tightly under wraps.
The restriction stayed in effect until 1 October, covering an area near the infamous Extraterrestrial Highway - the stretch of Nevada State Route 375.
Joerg Arnu, an Area 51 super-fan and researcher who closely monitors activity around the base, said he overheard staffers discussing a decision to lock down the base on the day of the incident.
According to Arnu, he heard people say that an asset had gone down and comms referenced an 'unmanned aircraft with ordnance' was involved.
After heading to the base, Arnu found that the Tikaboo Valley had been completely sealed off by armed patrols. Sheriff's deputies backed by military security were preventing anyone from approaching the area.
Following the investigation, officials added that some individuals had scattered unrelated debris at the crash site which, of course, raised questions.
Arnu argued: “I think that was designed to make people not go there, discourage people from going there.”

George Knapp, the chief investigative reporter for KLAS, also posted on X: "Anatomy of a crash retrieval. When a mysterious object crashed outside of Area 51, USAF teams sprung into action, locked down the base and this valley. Almost everything told to the public was false."
