Could this be right? Chemtrails are said to vary from contrails in their length of persistence. Chemtrails do not dissipate quickly; they tend to form into mushy clouds which can block sunlight.
Some people are reporting what they describe to be unusual activity in the sky, including jets leaving trails at low altitudes, spray lines creating X's, S's and parallel lines, lines that slowly spread to create a canopy of haze, and reports of unusual smells, tastes, and even illness related to the trails.
