"Contrails -- the white line clouds created from condensation by passing jets -- caused you to be sick?"
Aerial dispersion is a great way to dump toxic waste.
Yeah, I've seen a lot of toxic waste trailers pulled up to my plane when I'm leaving on a trip. Those airlines just love loading that stuff in there. And what's really incredible is that not a single member of a ground crew or flight crew from any airline has ever exposed this massive conspiracy.
Although I suspect they just teleport the toxic waste into those hidden dispersal units just before takeoff. That way, no one need ever know....
