If you’ve only seen the short lived and high varieties you’ve missed out. I don’t know the US, did you live somewhere dry? That could account for this.
I've watched countless WWII movies over the years and never saw contrails in them, except for the occasional 2-second wisp from a wing tip. It's clear to me that the massive propaganda machine is at work altering and adding to old clips. It's nor surprising. It's exactly what I would do if I was in their position. I've seen some of these clips lately, and they are clearly overcompensating. They are clearly propagandistic.
Why would they waste enormous sums of money to dump this stuff over uninhabited land which is not even used for agriculture and so would never enter the human food chain?
Because chemtrails are not just about human intoxication. They are also about ionizing the atmosphere. This may be for underground mapping and other purposes all being accomplished in one program. I'm not sure because it's obviously a "secret" (HIPS-hiding in plain sight) operation.
See the sticky posts that I have in this forum regarding these patents, or you can do a Google search. The use of barium in th atmosphere has some amazing implications.
About the money, you need to realize that money is no object. The scope of this operation (global) demonstrates the enormous political power behind this. In fact, it is evidence of a centralized world power, just as predicted in the Bible. Only a world power would be able to control most nations of the world to participate in such a program.
Metals are long lived environmental pollutants so you don’t have to drop it constantly to get an effect.
Yes they are, which is why we are now seeing so many soil tests come up with very high aluminum, barium, and other toxins.
"And the nations were angry, and thy wrath is come, and the time of the dead, that they should be judged, and that thou shouldest give reward unto thy servants the prophets, and to the saints, and them that fear thy name, small and great; and shouldest destroy them which destroy the earth."(Revelation 11:18)
Forget 15 minutes the particle sizes they documented would take days to fall from thirty thousand plus feet which is the altitude they claimed for chemtrail spraying.
They are spraying low here, for the most part. I occasionally see them spraying high, but I can feel the intense sinus burn usually 15 to 30 minutes after they spray.
The other problem I see with this idea, and it’s the one that started this thread, is the question of how you know what’s in the chemtrails. How do you sample them?
Simply because there should not be those kinds of levels in the atmosphere. When several tests have been done in different areas they are spraying, and we continually see these metals appearing "out of nowhere", we can start to draw some common sense conclusions.
Let us not forget common sense.
