Thanks for your opinion, but you are wrong.You’ve posted this thread several times. The truth is when hot hair and cold air meet from the airplane exhaust it causes condensation. When different air pressures from the wings hit they create condensation. The reduction in pressure and temperature across each vortex can cause water to condense and make the cores of the wingtip vortices visible. This effect is more common on humid days.
It’s - 50 degrees Fahrenheit at 36000 feet where most commercial aircraft fly. The water vapor has a large surface area allowing for quick heat exchange which results in frozen vapor, aka clouds. Clouds persist based on atmospheric pressure, atmospheric temperature, vapor amount, humidity, and amount of heat from the source (aircraft).
You’re seeing more of them bc there are more aircraft, flying in similar flight paths, that are larger and flying higher than ever before.
That’s it. There’s no conspiracy, no government poisoning plan, no agent orange type massive spraying. That’s the truth. That’s it. Nothing else.
It’s literally heat exchange that’s it. Heat exchange happens around you every single day.
