2007-09-04 - Newbridge (Gwent) (UK/Wales) - Sphere

sphere flew overhead stopped manouvered at impossible speed changed shape and left at high speed

i was sat in my garden when i looked up and saw a large white sphere that seemed to stop in mid air fly in a zig-zag in the same position rotate and change shape then leave at at least mach 4 there was no sound and it appeared to be at aircraft cruising height,i lost sight of the craft as it flew towards the sun.this was not a bird or a plane it seemed to stop as i looked at it,wierd.i would say it was very large ,after spotting aircraft in the same area it appeared to be twice the size of a airbus 747 in diameter and the sight of a metallic flash was also apparent as it changed shape (it kinda had a silver ring appear around the centre of it that gave it a saucer like appearence with a upper and lower white dome).i was a seargent in air cadets and know how to identify known aircraft,and having flown myself so i know this wasn`t manually controlled by a human being radio controlled maybe but it was huge!high! and fast!
