@gol979 According to the believers in this ludicrous conspiracy theory, every aircraft that leaves contrails (i.e. all of them) must be engaged in "stratospheric aerosol injection/cloud seeding/geo engineering". That is utter twaddle. When you burn hydrocarbons, you get carbon-dioxide and water: it's as simple as that. First-year science stuff. The irony is that it's aviation contrails that are wrecking the planet.
@gol979 That it has been done experimentally, decades ago, I have no doubt. It doesn't follow that the condensation trails produced by every aircraft in every country on the planet are part of some insane conspiracy of the global elite to...do what, exactly?
