My understanding is that these bills would make that illegal.
Pretty sure that the actual components of airline exhaust would be considered legal. They wouldn't just ban all fossil fuel powered flight, they just want to ban the non-existant mind-control/climate manipulation they think the airplanes are doing.
The injection, release, or dispersion, by any means, of
a chemical, a chemical compound, a substance, or an apparatus
into the atmosphere within the borders of this state for the
express purpose of affecting the temperature, weather, climate,
or intensity of sunlight is prohibited.
These people think that jet contrails are like, mind control chemicals being sprayed by airplanes flying over. That's what they're trying to ban, something that isn't even happening.
