Original Note:
These contrails are made up of water in the form of ice crystals. They form when water vapor from an aircraft's engine exhaust mixes with the cold air at high altitudes, causing the water vapor to condense and freeze into ice crystals, not heavy metals. https://www.faa.gov/sites/faa.gov/files/regulations_policies/policy_guidance/envir_policy/contrails.pdf
