Contrail Persistance and growth
Many chemtrail theorists claim that contrails do not spread out, but
chemtrails do. This is very untrue and shows a lack of knowledge of how
the upper atmosphere works. If the atmosphere is moist enough to hold a
contrail for an extended length, chances are that it will spread out to cover
sky, forming a layer of cloud known as cirrostratus. If the atmosphere is
dry, then the contrail will fail to persist and growth will not occur or will be
limited. It should be mentioned that weather balloons are used to retrieve
data in the atmosphere, then that information is used against the
Appleman chart for forecasting purposes.

There.
