My brother-in-law is a contractor and his work takes him to various AFBs around the world. He has seen first hand the spraying nozzles and speaking with ground crew was advised that it is hydric acid that is being dropped on us. Apparently it was something used widely in agriculture (probably to contaminate the food) until it was banned. I’m no chemist, but dropping acid can’t be good for anything. Caught these chemtrails this morning, you can even see where they stopped spraying briefly, probably changing between tanks! Hope this helps.
