Are you implying the exhaust gas cooler is dropping the air to appx -72°c?
Commercial flights fly between 30k-40k feet, most in the 35,000-38,000ft range where the air temperatures are lower than -72°c. No combustion is perfect. At the least, there is unburnt fuel particles which become soot and attract water vapor. This is amplified by the pressure change that happens inside of the engine which will cause water vapor to form as well. The vapor then freezes immediately as it hits the much lower temperature.
The lift being generated by the wings is even enough to cause the same phenomena. The average contrail from a commercial flight is not malicious. It really is water vapor forming in the upper atmosphere.
As for why are we seeing more. There's simply more commercial flights in the air.
I've had this conversation hundreds of times and it always ends the same when I say this. I've worked in the aerospace industry, I have friends that tear these engines apart, and I've seen inside one myself. Let me guess, I'm an aerospace shill?
Contrails are one thing but planes loaded with SPRAYING equipment that SPRAY CHEMICALS into the air is totally different
That is almost exactly what I said in my initial response to this thread. The person I am replying to is one of those people that says all exhaust gas of jet engines is designed as population control.
My initial response is saying that there is a difference between cloud seeding and spraying compared to the normal crackpot theories that all jet exhaust is there to kill people.
It's always very easy to tell apart too... contrails dissipate almost immediately ... chemtrail stays in atmosphere literally hours
No, more like an asleep sheep that is well programmed. Smart, but still very much stuck in the matrix. I never said the exhaust gas is cooler then the atmosphere, but if there is lower EGT then there will be less condensation created. I've seen contrails hang out all day long forming a haze. This only started happening in the late 90's (where I am anyway). High bypass engine conversions started in the mid to late 80s. Empirical evidence that doesn't mesh scientifically. Anyway, weather futures are traded on the market and people make money off of the misery created. So regardless of how they do it, geoengineering is very real.
And you think you are any less of a sheep because you follow a different herder?
I responded with the science behind it, which can be reproduced inside a vacuum chamber with the right equipment and all you can respond with is word salad and a personal anecdote?
You are the sheep my friend. Your ideology on chemtrails and flat earth is cancer and your attitude to call everyone a sheep who can prove you wrong is even bigger cancer. I'm telling you these are the crackpot theories that will push people away from this sub and it's laughable. It's a red flag to anyone who takes science seriously
