House committee advances bill to ban chemtrails

Contrails are mostly water vapour that’s condensed due to the hot exhaust of airplane engines.
They are certainly not completely avoidable, they are likely inescapable without sacrificing significant fuel efficiencies (eg: all methods stealth fighters use to suppress or mask their exhaust heat signature)… which would negate any benefits to global warming.
P. s. I’m not going to watch a YouTube video that could be a few paragraphs of textual explanation, because it’ll no doubt be eight times longer than it needs to be for the benefit of more ad money or promotion in the almighty algorithm.
By simply re-routing planes around these cold patches, the contrails could be reduced.
And routes now are generally chosen to be the most fuel-efficient, subject to regulatory constraints such as avoiding overflight of areas of high population density. So any alternate path will be longer and burn more fuel.
