glowing white cigar shaped cylindrical objectIt was a long white cigar, cylinder shaped object in the sky. It could have been disc shaped and I might have been looking at it from the side but I'm not quite sure. it had a glowing white color like the kind of white that clouds have when sun shines directly on it, but just a bit more 'glowy'. It was going from north to south direction. at first I thought it was vapour from an aircraft, but at the tip of the vapour i could see no visible craft, and if it was vapour, the vapour was not getting any longer. I only noticed that it wasn't conventional aircraft when i saw the whole length of it move. it was huge. It moved behind a big cloud however and we lost sight of it. During that time, it was also beginning to rain. Right now we are experiencing some real crazy rain, so I'm not quite sure what the object might have been. I've seen alot of planes flying before, but just estimating and looking at it in the sky, it seemed pretty big, as a matter of fact around 5-8 times bigger then a 747. I'm kind of surprised no one driving next to me saw it cos they were probably concentrating on driving.
