A mysterious light hovering in the night sky over Gateway Arch in St Louis, Missouri, was captured on a security camera, sparking UFO sighting rumours among citizens. The moment was captured on a surveillance camera at Malcolm W. Martin Memorial Park and was uploaded on the park's official Facebook page on Wednesday (3 August).
Park authorities raised their suspicion over the unidentified flying object and captioned the video: "Unexplained Lights over St. Louis - We guarantee you will be perplexed if you watch all 5 minutes of this surveillance footage."
In the five-minute long video, a light is seen appearing out of nowhere and then descending, before it vanishes and reappears at another location. The object was spotted early on Tuesday morning and apart from the park's video many others claimed to have spotted the mysterious light. The video has attracted more than 500,000 views on Facebook.
Some viewers claimed that the light could be a drone. Jared Hill, who saw the footage from the surveillance camera offered a detailed analysis and concluded that it has no extraterrestrial links.
He wrote in the comment section: "It was a drone with a unidirectional light on it. Dude brought it up and over to the monument, then shut off the light for a minute, then brought it up and back and landed it. The light gets brighter when it turns towards the camera.
"The most important thing to consider when looking at this type of stuff is accel/decel. If it accelerates to thousands of mph and stops instantly, it is a legitimate curiosity, since conventional tech can't do that. This is just a drone with a light."
Another Facebook user speculated that the flying object might be a weather balloon. "Yes, it could be a drone....weather balloon/helicopter," the user said.
Fox2news meanwhile reported that Scott Air Force Base did not receive any calls of concern over unidentified flying objects and had an "ordinary" Tuesday.
