High flying object seen traveling at a high rate of speed.Object was traveling at a high rate of speed from the south west to the north east. It was very high in the sky, so high that its shape could not be seen. I could not hear any noise. It was very bright white in color. Flying in a very straight line. There was a very high plane laying down a chem trail traveling in the oppoiste direction. That is what I was looking at when I noticed this white object. It was a very clear day with a high sky and no clouds.
