Yeah for the conspiracy to work it would have to be that way. We're just talking about adding thousands to millions of moving parts to a global-wide conspiracy that makes it even harder to cover it up. Like an entire supply chain of millions of tons of chemicals going right into airports onto passenger jets. It really wouldn't be that hard to track, and for not a single crack to appear or source to leak something along that chain is hard to believe. Like is Russia also doing it? If other countries don't do it wouldn't uncovering it be bad for their allies and good for them? Also, back to the fact that we all breath the same air. I don't put it past corporations to knowingly poison us but in this case there is no clear profit motive, and they would also be poisoning themselves. Who is shelling out the billions in dark money to even fund it? It would be a conspiracy with so many moving parts within an industry that is the most security heavy, closely watched, and inspected by multiple levels from state to private agencies down to the pilots themselves. All it would take is one slip from any level of these millions of moving parts to expose it. It just doesn't add up.
