I have found out what they are spraying:
It is a fertility treatment!!! It causes males to be more horny, and females, specially young girls to get pregnant easier. I have the evidence too! Since 1996, when they stepped up the dispersing, the US population has grown, due to more births.
So it must be the power elites way to make more taxable citizens and more consumers for buying their stupid products. After all, who would want to kill of their base what there power is based on???
So keep your teenagers indoors when you see the planes coming!!!
