Full disclosure: I am prone to hallucinations during periods of psychosis, manic or depressive. I slip into delusion from time to time. This is not hallucination or psychosis or delusion. Not trolling.
Long time ago I knew somebody that worked for a govt. agency. He told me the government was working on weather control. He also referenced a historic weather event from before my time, and said he was almost certain it had been part of an experiment (based on what he was told to do). When he told me about it, I didn't believe him, mocked him, other people around told me he was telling the truth. Still remember thinking, "no, he's just trying to f*ck with my head".
Now not so sure. I don't know if that has anything at all to do with this next part, but call me suspicious. I have always linked the two in my mind.
Around the mid to late 90's I was out one day, and I noticed something odd about some airplanes flying around. All day they flew around spraying stuff. They weren't nearly as high as most of the normal air traffic, and whatever they left behind them was not normal. It almost looked like shaving cream that froze, and hung there in the air. Even stranger, there were planes flying side by side (one leaving a trail, one not), odd patterns being left...
I noticed it off and on over the course of a few months. Showed a couple of other people, one time it was so obvious that something abnormal was going on that the person I showed stood there gawking for an hour or so. I know about contrails; this is not what I saw.
Few months go by, I saw an article about it in a newspaper (poking fun at the silliness of the idea iirc). And shortly after that, I discovered the Art Bell show on AM radio, heard it discussed (discredited?) there. That was right about the time the dramatic, obvious stuff stopped.
Really started to mess with my head about real contrails. Most of what I would see was normal contrails. Still, every once in a while I would see something, watch a little closer, and go yup...that's what I saw. More discreet about it, but...
Now it seems like it has sort of spawned a ufo type following. Talked to person about it in my family, come to find out he is a big believer in Chemtrails. We are standing there smoking one day, watching completely normal jet contrails, he's going "Look! Look! They are spraying again!", and I just stood there and shook my head.
So help me god, if anyone dares to explain real contrails to me, or post WW2 pictures of contrails...
I know chemtrails are a conspiracy theory.
