On Friday night, SpaceX launched its latest rocket and caused a bit of a panic in Southern California and Arizona.

The launch, which was SpaceX’s final launch of 2017, saw the Falcon 9 booster take off from Vandenberg Air Force Base at 5:30 pm. 

The rocket was carrying 10 Iridium communication satellites which were deposited into space.

Although it was a routine launch for the space exploration company, this one created quite a sight in the skies above that region of the United States.

The rocket soared through the early evening sky leaving behind a trail of blinding white light that looked like something straight out of a science fiction movie.

This #SpaceX launch from Vandenberg Air Force Base was exactly 800 times cooler than I thought it would be. This was the view from Old Town Pasadena. Thanks to ABC7 Photog Jamie Evans for the Video. #rocket#UFOpic.twitter.com/PbtqWki6J7

Not knowing what it was, people soon began to jump to conclusions on Twitter. 

Aliens were a very popular theory.

Others, worryingly, thought that North Korea was attacking…

Space X needs to do better job of warning us before their launch. Was convinced UFO or North Korea was in our air

— Patrick Shriver (@PSchwarzenegger) December 23, 2017

Why doesn’t @SpaceX tell us before they launch some shit so we don’t all think North Korea is bombing us? #SpaceX

Residents soon began to call TV stations and local law enforcement agencies with concerns about what was going on in the sky above them.

The Daily Mail reports that at least 130 people in a particular area of Los Angeles County called 911 about the incident. 

Although there was nothing at all to worry about the LA Fire Department did advise citizens that the “mysterious light in the sky” was from the rocket and nothing else.

Once they realised everything was OK, everyone seemed to have a lot of fun with the hysteria the launch caused

*Alien invades Earth*
