Footage uploaded to conspiracy YouTube channel SecureTeam 10 shows a plane travelling through the sky before completely vanishing in an instant.
The footage was captured in Birmingham, Alabama, by a man who, according to the narrator of the video, was out walking his dog with his fiancé when he began filming a passing train and then turned to what he thought was a commercial airliner.
The narrator says: “Then this airliner does something what no airliner has been seen to do, which is completely vanish in mid air.
“I have spoken to the three sources, in depth, from Birmingham, who after capturing this footage did not run out to put it online or give it to their local news source because these weren’t those type of people – they had no incentive to do so.”
The footage is apparently not an isolated incident, according to the operator of the channel, who says that he is constantly inundated with sightings of ‘alien planes’ which have the ability to disappear or morph into a new form.
It says: “This is not the first time that we have seen these fake planes, or another term alien planes.
“They have been seen all over the world.”
One of the comments confirms: “I s**t you not I saw the SAME exact thing over Birmingham just a couple months ago.. Thought I was going insane!!”
While some believe that the technology is out of this world, others believe that it could be part of a government conspiracy.
A comment reads: “EVERYONE BEWARE they are probably testing these technologies to simulate another catastrophic event like 9/11.”
However, others did not believe that the footage was genuine, with one asking “ever heard of CGI?”.
Another adds: “Who the Hell randomly films a plane seconds before it disappears? Cmon men.”
