The story goes like this: tens of thousands of commercial airliners a day are deliberately spraying some kind of mixture of toxic chemicals — either across the United States, or possibly globally — in what would amount to one of the largest covert operations ever.
The scheme has been going on for years, perhaps decades. The goal: everything from large-scale weather modification to mass population or mind control.
The motive presumably would vary with the goal, but it is typically seen as a version of powerful business, government, and military interests covering up even worse deeds.
And guys… This is true!
