There's plenty of evidence most commercial planes don't use Jet fuel I haven't looked into this in a while and ya'll really need to look into it yourself but off the top of my head:

There's not enough space in wings or fuselage for required oil as listed on Wikipedia.

Fuel would move with the plane turning.

Why no fumes?

A leaked video showing an air compressor instead of the fuel pump at an airport.

The weight of the fuel would tear the wings off since they're so far away and there's very little support.

To top-up the wings with enough fuel as quickly as they do it would require a hose at least 5x faster than a fireman's hose - which would blast right through the metal and make lots of noise.

Do a rough figure of how much fuel a 747 uses during a flight, then work out the ticket sales, factor in tax, pilot income, plane technician income, 'fuel cost', etc. and the tickets only make up about 30% of the gross expenses (and this is a lowball figure if you consider discounted flights and expenses I forgot about).

Why would they lie about it? Massive, Massive profits - flights are super-cheap since fuel costs are just electricity for an air compressor. (turbine powered by a compressed air tank in the wings which causes the turbine to spin)

Globalization and mass migration would be virtually impossible without the global airline industry, it's fast.

Think. Have you ever seen or heard about an oil spill? Have you ever seen a truck filled with jet fuel? How do they transport it? Supposedly they're burning millions of gallons a day or something? We'd have seen it and known about it.

The blueprints and explanation for how a jet engine works don't make sense. How do they make hydrocarbons create the spin for the turbine? - There's no crankshaft and they even admit they're started by a compressed air starter.

How is this hidden? Simple. The airline industry is run by a handful of corporations, and the only people who could gather evidence have their phones monitored ('refueling technicians'), airline CEO's either don't know, don't care, or are part of it.

There are to-scale commercial RC planes that work exactly as I described and look exactly the same in terms of how they lift-off, fly, land, and sound as regular planes. There are videos on youtube of conventions and the guys are smirking and laughing - probably doing a whole freemasons 'in the know' comedy/hobby thing.

Have you ever heard of a plane having an oil spill? Is there a picture or video of it? No, because it doesn't exist. I'm not saying there aren't combustion planes with engines (there are countless WW2 planes like this for example) - but they're loud, way more expensive, require fuel, and have a much shorter range (because of the extra weight and less efficient and less advanced method of propulsion).

Smaller planes can handle the 'sloshing' of fuel in small tanks, larger planes wouldn't - also airport security around passenger aircraft is insane but if small aircraft were also a scam then it wouldn't stay a secret for long.

There's obviously jet engines that use jet fuel, but those are Crazzy expensive, even for smaller fighter jets and you can see, smell and hear things such as the heat of the air burning, flame (if afterburner especially), the smell of burning jet fuel, the much different sound of a jet engine vs an air turbine engine, etc.

It costs about the same to fly a 2 man combustion plane per mile as a 747 if you're accounting only for maintenance/fuel costs. Here's a good start, for anyone interested: https://www.bitchute.com/video/Vr1JbHt0ZXwp/
