I almost didn't bother reading this story, but when I realised it included the footage of the reported 'UFO sighting' I changed my mind.

Mystery as UFO footage emerges | Glasgow and West | STV News

The clue for me is the diamond shape of the artefact, described thus:

Quoted Text

John McGregor, who lives in the Whiteinch area of the city, has decided to release a video he filmed in 2006 in an effort to find out more about strange diamond clouds moving at speed.

In his film, shot on a camcorder, the object can be seen moving quickly across the sky with white lights flashing occasionally from it. John, who is in his 50s, told STV News he believed the objects were military aircraft, and the lights were weapons being fired.

He added: "I have seen the objects several times since 2004, the most recent time being in January this year. I was just watching TV and went over the window and saw this object, so I got out the camera and started to film.

I believe things happened the other way around in reality, and he saw the diamond shape, and convinced himself he saw it before looking through the viewfinder.

All I can see is normal lens flare, where a light source off camera is producing a visible artefact unrelated to the actual scene being viewed.

This can easily be confirmed by watching the movement of the artefact which, without too much effort, can be seen to be related to the movement of the camera, which is (as nearly always seems to be the case) not being held very steadily. Why do those recording such scenes not just stand still once they have the 'object' in view, but seem obliged to shake the camera around as if it was hot?

Watching the artefact, it has no motion that suggests it is flying, and its focus, or rather lack of focus, also shows the artefact is not something at the same distance as the clouds.

You could probably lash something together to do something similar, although the diamond shape depends on the lens, so this could change depending on the manufacture.

This one's not hard to trash, without even trying, and I'm surprised it has lasted since 2006 or so without an expert debunking the story of aircraft with guns blazing away.

Then again, maybe not, since Flying Rods or Skyfish have been around since 1994, and while they really just insects caught on video, they can still be found online being presented as:

They may be all around us... in the sky, in the water, even in our homes. They have been captured only on film and videotape. No one knows what they are, where they come from, whether or not they are alive, and they have never been touched or seen at rest.

They are called "rods," "skyfish" and sometimes "solar entities." Although the video evidence is compelling that they are quite real and probably living creatures, they are completely unknown to science - a fascinating and baffling mystery.

Skyfish and Solar Entities
It seems to be getting harder to find video online quickly, as filmmaker José Escamilla is milking his footage for all it is worth in TV appearances, and perpetuating his 'discovery'.

Even on his own site Roswell Rods the footage is now private, and cannot be viewed directly.
