You keep saying contrails are caused by freezing water in airplane exhaust... Since when did airplanes start using water for fuel? So even without additional geoengineering salts being sprayed behind a plane, what comes out the exhaust is definitely full of chemicals, not water. Not too long ago they even put lead in jet fuel to make it burn at a higher temperature. So how do you really believe it is just harmless water, and not a chemical cocktail coating our sky? I would love to get my hands on a water powered car or airplane if you know how to make that happen!
