Actually they are not called “chem” trails but “con” trails, “con” being short for “condensation”. The trails are not jet engine exhaust, but the water vapor in the atmosphere that is compressed and condensed by the jet engines, which turns into ice particles at high altitudes. Turbocharged piston engines will do the same thing.
