Fastwalker over the UK
This is a typical example of a high-flying fastwalker moving across the sky. Sometimes YouTube hoaxers will video a satellite, then alter the speed of the video. It does not appear to have happened here. The creator of this video provided an excellent description of this videotaping session:
Using a Pulsar Recon 550 digital monocular and a Yukon MPR, what was initially thought to be satellite was tracked and film. You will see in the footage that the first object is quite faint but you can see it moving in a straight line through the shot. Then a second object moving much quicker enters the shot but as it moves parallel to the first object and too the right of it, it suddenly moves away from it. It clearly increases its distance from the first object.
