A video, which was posted on the popular social networking site Youtube, and said to have been recorded on Friday, 24 June near the BBC Radio One building sent the web into frenzy. The film, shows bright disc-shaped objects dashing through the blue skies over central London, and the network users insisted the video showed not just any UFOS, but 'a mothership and its fleet'.
Another video was later on posted online and showed a similar number objects in the skies over London's Tower Bridge.
However, putting an end to the debate on the real nature of the footage, Benjamin Radford, Deputy Editor of "Skeptical Inquirer" science magazine told space.com that the mothership and its UFO siblings videotaped over London are almost certainly fake ones. Radford also added that glowing ovals and dots are some of the easiest images to make up.
There's no detail, he said, "no flying saucer windows or aliens waving hello from high above. Just white moving dots that anyone with some video-editing chops could create with little effort."
He continued: "Another sign that this is a fake is the way the video begins. The cameraman is apparently randomly videotaping a mundane sidewalk, and then moves quickly to a street corner, where he takes careful note of the reactions from passer-by before aiming the camera up into the sky to see what, exactly; it is that has so captivated their attention. He videotapes the skies for about a minute, then once again brings the camera down to show us a small crowd of people who are also staring into the sky and getting photos."
"This is highly suspicious behaviour for someone who truly believes that there are alien spacecraft in the skies above that could reappear at any moment. If you spotted what you believed to be a UFO that could zip away at any moment, wouldn't training your camera on the spaceship be the first thing you would do? Whoever created, edited, and posted the video clearly wanted to make sure that viewers knew that others had seen, and were reacting to, the lights", added Mr. Radford.
Others have suggested that the video clip might be a marketing tool for the forthcoming alien sci-fi film, "Iron Sky".
