“Unbelievable, not sure if it’s a jet or some aircraft I haven’t seen before. Pretty cool nonetheless.”
As Rachel is situated so close to Area 51, conspiracy theorists obviously linked the two together, claiming it must have come from the top secret military base.
Prominent alien hunter Scott C Waring wrote on his blog UFO Sightings Daily: “The sound is just like that of a jet, but clearly the object is a metallic disk.
“So perhaps the sound is merely the noise of the UFO pushing aside the wind as it shoots across. Clearly another top secret Area 51 project.
“Imagine a fleet of these American craft flying over other countries. Puts the fear into those who see them.”
The sighting comes just as two million people have signed up to an event on Facebook called ‘Storm Area 51’.
According to the description of the event, attendees will meet nearby and storm the top secret base on September 20.
The description reads: “We will all meet up at the Area 51 Alien Center tourist attraction and coordinate our entry. If we naruto run, we can move faster than their bullets. Let’s see them aliens.”
Although the Facebook event is meant to be humorous, US military is not taking any chances in protecting the top secret base.
Air Force spokeswoman Laura McAndrews said: “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.
“The US Air Force always stands ready to protect America and its assets”.
