Storm Area 51

Storm Area 51, They Can't Stop All of Us was an American Facebook event that took place on and around September 20, 2019, in the desert surrounding Area 51, a highly-classified United States Air Force (USAF) facility within the Nevada Test and Training Range.

The event, created as a sardonic shitpost by Matty Roberts on June 27, 2019, asked Facebook users to band together and raid the site in a search for extraterrestrial life that conspiracy-theory lore claims may be concealed inside. More than 2 million people responded "going" and 1.5 million "interested" on the event's page, which subsequently attracted widespread media attention and caused the event to become an Internet meme. Roberts later stated his intentions for the event had been purely comedic, and disavowed responsibility for any casualties had there been any actual attempt to raid the military base.

On the day of the event, only about 150 people were reported to have shown up at the two entrances to Area 51, with none succeeding in entering the site. Two music festivals were planned to coincide with the event: Alienstock in Rachel, Nevada, and Storm Area 51 Basecamp in Hiko, Nevada. An estimated 1,500 people attended these festivals, according to state and local law enforcement. Air Force spokeswoman Grace Manock stated government officials were briefed on the event and discouraged people from attempting to enter military property. Nevada law enforcement also warned potential participants against trespassing. The event had an effect on businesses both locally in Nevada and around the United States, which prepared products for visitors and those attending the event.
