When not to walk the dog I looked up in the sky I saw will look to be a star moving in the direction from north to south I thought it was a plane as it moved little bit behind it follows another one and right behind that one the same distance and other another one and another one on a straight line without moving they followed one after the other perfect motion there must have been about 15 of them has it moved across the sky imperfect sequence I don't think plants do that with the same distance apart same speed they never change color just look like a little white. Wait about 15 right behind it fall in straight line no sounds of aircraft have a really high in the sky
