UFO Sighting: Swarm Of 'Giant Orbs' Fly Through California Sky

People in Chino Hills, California were left stunned after witnessing a possible UFO sighting.

According to a video above obtained by TMZ, multiple giant orbs or lights flew around in the sky, moving in strange patterns and circling each other.

Eyewitnesses say there was no light source coming from down below. They also told TMZ that after about 30 to 40 mins of the lights moving in the sky, they completely disappeared without a trace.

The unexplained incident was caught on video on December 9, around 9:00 P.M. The woman who captured the footage told TMZ her grandson was taking the trash out when he looked up and saw the fleet of lights.

Shocked by what he saw, he made the rest of the family come outside and see it for themselves.

The witness said she thought there was a grand opening happening but they couldn't find any events nearby.

While there's no immediate explanation for the creepy orbs floating around, there has been a similar sighting by a pilot.

According to TMZ, the pilot said the orbs he saw were flying above the clouds, which you can see in the video below.

Apparently, sightings like these are becoming more common and the Pentagon is dedicating a new wing to studying them.
