@I_Am_The_ICT Hell Yeah

Are you ready to learn how I smashed the daily High and shorted the full daily range? Give me a "Hell Yeah"

@I_Am_The_ICT No NDA. Jet engines produce water vapor as a byproduct of combustion. At cruise altitude it freezes instantly. Whether it dissipates or spreads depends on upper-level humidity. I respect you a lot. I can only speak from my professional training and what I’ve seen in the cockpit.

Do you believe what you posted here or are you under an NDA? It's fairly obvious planes are spraying the skies with something and it is not contrails. When I was a boy, I would watch planes fly all over the sky and only the very high flights would leave a short temporary trail that disappeared. This stuff spreads out and covers the sky with a milky haze. I can't accept your reply as true.

I am curious... Are there any Commercial Airline Pilots reading this?

@I_Am_The_ICT I don’t believe planes spray anything, the lines are created by condensation from the engine exhaust. We sometimes even get specific routings to minimize this effect.

@tim_otheos What are these lines being sprayed off the planes flying around?

@I_Am_The_ICT Yes, I fly for Lufthansa in Germany

@tim_otheos Are you a pilot?
