The number of people signed up to storm Area 51 and "see them aliens" has hit 1 million.
The Facebook event 'Storm Area 51, They Can't Stop All Of Us' hit the 1m mark on Monday (NZ time). Another 850,000 say they're interested in the event, which is scheduled for September 20.

"We will all meet up at the Area 51 Alien Center tourist attraction and coordinate our entry," the page reads.
"If we Naruto run, we can move faster than their bullets. Lets see them aliens."
Naruto is the lead character from the self-titled Japanese manga series, known for his distinctive running style.
However those attempting to storm to the highly-secret base have been issued an ominous warning by the US Air Force.
"The US Air Force always stands ready to protect America and its assets," spokeswoman Laura McAndrews told the Washington Post.
"[Area 51] is an open training range for the US Air Force, and we would discourage anyone from trying to come into the area where we train American armed forces."
No one outside of the US military really knows what goes on at Area 51, located in a remote part of Nevada. The best guess is experimental weapons testing but, since the 1980s, it's been rumoured to be the resting location of an alien spacecraft which allegedly crashed in 1947.
