The missile trails across the sky

option A would be so simple to tell the public, they would have said that already.
option B does not fit 1) the enormous change over time in the patterns that settle into this sort of fog, which did not happen earlier in my life or 2) two planes at the same altitude, one with a dissipating trail, one with a trail that, stays, spreads and becomes cloud cover when crossed with others.

They probably did say that, and people dismiss it as a conspiracy. My guess is it’s a different kind of fuel that happens to be cheaper and more efficient but more harmful to the environment. There may be a bit of a cover up on the part of the airlines to deny the evidence of environmental harm, but I’m guessing that’s the extent of it.

That is a conspiracy and they would be stupid not to reveal the lesser evil. but of course governments are often stupid. The problem with this explanation for me is that there are patents out for weather modification using amongst other things certain heavy metals. using such a process would lead to trails like those we see AND lead to high amounts of the specific heavy metals in the patents being found in places in nature where there could be no other source but air dispersion. I am not certain what they are doing or why, but they are not being honest about something. Hopefully it is more minor as in your particular conspiracy theory.

That depends on the legal and business ramifications they’d face. Polluting the environment might be the lesser evil than lying to the public, but they’d probably face greater legal and business penalties by being honest (like chemtrails being banned). Business always has a different set of morals than regular folk. The only moral value business knows is the bottom line, and if they stand to make more money by lying, they’ll do that.

Absolutely, but in this scenario, it’s a corporate conspiracy, which means government doesn’t necessarily know about it. When corporations conspire, they typically want to keep it hidden from both the people AND the government.

Now the more insidious (and interesting) conspiracy is by the water treatment plants. Did you know that the water that comes out of your faucet contains not only a whole swack of consciousness altering drugs, but nano-bots carefully programmed to target your brain and take control of your neurons?

Just come to the United States walk in any public park and stare at the sky all day.
