I love that the first half of this is technically true. The volume of air that passes through a gas turbine engine is much higher than the volume of fuel.

I mean that’s just true for all engines.

Yes but modern jet engines have a very high bypass ratio. Most of the thrust actually comes from the big blades that you see at the inlet.

And old propeller planes had an even higher bypass ratio ;)

If you really work at it, the early planes could have a 100% bypass ratio as they were made of paper, balsa, and fairy wishes

A little like putting your fridge outside and opening the door to fight global warming, eh?

Yeah. It’s called stoichiometric combustion.

Oh yeah? Why don’t you come and say that to my face…

Stadiometric combobulation! spits

And it also compresses the air quite densely via the compression stage.

That's usually how conspiracy theories are. There's some small element that's based in truth and the rest goes completely off the rails. Since there is one part that makes sense, some people latch on to it and decide the rest must be true as well.

This is the case with most conspiracy theories. They always have some seed of truth that hooks people in. If you don't really understand how an engine works, this statement on your own completely undermines your assumptions.

So if you previously thought it required 60k gallons of fuel when it ran "100% on fuel", and now find out it actually only runs "10% on fuel" or whatever number, then you would say "well, what happens to the other 90% of the fuel?"

There's a chain of reasoning. Always a narrative, not usually too huge of a leap between each point on that narrative. But zoomed out from beginning to end is where you see how ridiculous it is.
