Yes, and passenger jets run on compressed air.
I stumbled across that conspiracy theory as I was wandering YouTube and couldn’t believe it. I thought conspiracy mongering had hit its low with the 9/11 truther idiocy, but I was wrong. And once I had viewed that moronic video, of course it suggested others that were similar, which opened my eyes to how truly stupid many, particularly the Millennials, have become.
I suspect some of these conspiracy videos are just concocted by scammers who want to take advantage of the pathetically gullible (of which, judging by the video comments, there are many) in order to fish for views, but others are clearly posted by true believers. Regardless, the number of commenters on the videos who buy into this crap is scary.
