'UFO' shocks plane passengers
A white object has been filmed darting around the skies of Seoul giving plane passengers a fright.
A clip of the incident above South Korea was uploaded to YouTube on April 7.
At the start of the clip the white object keeps pace with the passenger plane before gathering speed and altitude.
Just as the person filming the object tries to zoom in, it disappears out of shot.
So, is the video a fake or the real deal? Maybe we should ask YouTube user Pseud0Name, who wrote: "When stabilised, it is easy to see what is going on with the video."
"The edges of the UFO are not blurred like all of the other background objects, it seems like a separate effect from the background, and in fact you can see edge noise on the shape of the UFO indicating it's a fake."
"It doesn't even look right if you start to look at it hard, especially slowed down frame by frame."
A user going by the name of vicariousjojoe agreed, decrying: "People, you should know by now what is fake and what's not. You can always tell by the way the camera moves and zooms."
