If you’ve ever seen a jet fly across the sky, you may have noticed that there is sometimes a thin white line behind it. These clouds are contrails, short for condensation trails.
Water vapor is one of the byproducts of jet fuel combustion and will turn into ice crystals in the cold air at the high elevations where jet airplanes fly. Those ice crystals create a cloud (the contrail), which does not pose any public health risk.
Contrails can evaporate quickly if humidity is low, or they can linger, and even grow by taking in water from the surrounding atmosphere, when humidity is high. (Ref: azdeq.gov)
