One theory is that the global elite actually believes the global warming hogwash. They are trying to cool the planet down for us the peasants. They have told the pilots and drone pilots that it’s a matter of national security (happening worldwide). Even if they’re doing it for humanitarian reasons, there are always unintended consequences.
Other possibilities include using chaff to block radar and weapon use. Or, the Agenda 21 slow-kill of millions (or billions) of us. More money for some along the way, fewer of us to get to their dream population of 500,000 worldwide.
Who are the pilots they have told that to?
