Ask The Weatherman for September 11, 2013:
Question: What makes jet contrails in the sky?
Answer: When you notice an airplane flying overhead and behind it is this great looking white thin cloud, this is known as a jet contrail Contrails are made by the moisture from the exhaust of the airplane interacting with air particles at that level and create condensation which leads to the formation of the jet contrail.
