UFO Above Bishopbriggs 081109 Video

Saw this UFO in the skies above Bishopbriggs, Scotland in the early hours of Sunday morning, 08/11/09. Can't explain what it was and I had the camcorder set at 10 x zoom initially. I pull the zoom back to normal magnification a couple of times to give some perspective on the height the object is at (~10,000 feet plus?). It's moving too fast and in too many directions to be a standard aircraft or helicopter and it pulses and changes colour. Don't know what it is but please make up your own mind. This is not a hoax!!!
