Huge 100s of ft in the air as it was concealed by clouds on its course

White halo or sphere giving off no light , like paper white but so clear , as if it was drawn in the sky with white gloss, so fast at first I thought it was a mistake (like something in my eye) but it was perfect, no distorted sides , no beams of light , no noise at all , like someone had hit a massive ping-pong ball super speed in one strait line.  Only way I can describe it is to say it was matt , like no light bouncing off it or being emitted just a perfect white ball going at 1000s of miles an hour
