a CONTRAIL because you can see the vapor coming over the wing. The foggy conditions most likely brought this on. I've actually see a CONTRAIL while looking out of a plane window before as the atmospheric conditions were just right to cause that water vapor to form. Which is basically what a CONTRAIL is. However, CHEMTRAILS are very real and there IS a difference. When watching a plane make a CONTRAIL you can see it dissipating as it moves across the sky. However, when watching a plane that is spraying a CHEMTRAIL that substance stays aloft and DOES NOT dissipate for quite a long time. I've seen CHEMTRAILS that have lasted over an hour or more. Contrails don't do that.
