Unknown Object Seen by Two Witnesses in Great Britain

The second time we saw it was about 15 minutes later and it was about another 2-3 miles north away from original sighting. This time it was white again and just hovering still. It looked smaller. My friend commented that it was a star, until it suddenly turned green and shot off at great speed from a standstill in a straight line to the east. I ran through house to back garden to see it disappear out of view behind houses.

Again, the object made no sound nor did it leave any trail and both times it just suddenly turned from white, red, green, white green before zooming off – we were both quite shocked by this as it did not appear to be our technology.

I did manage to take a picture of it the second time but it just looks like a star in the sky – this was before it moved off, green at incredible speed. I also managed to get a short video clip of it the second time, but you cannot see it on the video as it too dark. I estimate it easily covered 20 miles of sky from standstill in about 7 seconds before going out view.
