Chemtrails or contrails (condensation trails)? Conspiracy theory or misinformation? White trails crisscross our clear blue skies every day. Who is behind them, and why?

Others believe that contrails, or vapor trails, are produced from a combination of water vapor and jet engine exhaust. We invite the general public to examine the evidence collected by experts in wide-ranging fields, from climate change to meteorologists.
