Long persistent contrails. Now, fuel dumps. I cannot refute either explanation, yet I cannot deny the documented evidence for geoengineering ... so back to agnosticism.
The topic of chemtrails has become way too complex for me. When I was younger, I'd research the heck out of something until I got a satisfactory accounting. But I'm 54 going on 96. While the topic is important, it's not at the top of my priority list. Here's hoping that someone else interested in the truths and the state of the world, picks up the mantle and resolves the uncertainty. I gave it my best shot or as much time as I'm willing to give. Ross has given reasonable explanations for the visual data to counter my arguments and findings on the topic of chemtrails. Offending or defending the nonvisual data would require a great commitment from all sides of the debate, a commitment that my side (and I mean only me here) cannot give.
So for me, agnosticism, and drinks at the watering hole ... it is.
