I was playing computer games at a friend’s house when he noticed something out of the window on the horizon. When we couldn't work out what it was he got some binoculars so that we could see more clearly (we got a very clear/close up look at it for a long time). What we saw looked similar to the space ship from the film 'Flight of the Navigator' but with small wings and three black dots at the back. It was shiny silver and metallic looking. It flew slowly travelling in a southeast direction at a height of about 2000 - 3000 feet (I guess) and took about 5-10 minutes to get from one horizon to the other.

The strangest thing about it was the way that it moved, it rolled and twisted in and unnatural manor which gave me the impression that whoever was piloting it was having trouble controlling it.

This maybe a coincidence, but it seemed to be heading towards RAF Croughton which is near Brackley. Have a look at RAF Croughton on Google Maps and you will see some very unusual patterns on the ground - apparently there is a large underground complex there. Since seeing this I have studied many photos of weather balloons and I am 100% certain that it was not one of these. I have also look a many other photos of UFO's and I haven’t seen anything that looks the same.
