Partially correct. What is suppose to happen to the water vapor trail once it reaches the atmospheric temperature?
Has everything to do with temperature. That is why the exhaust coming out of your tailpipe doesn't create a 20 mile long trail spreading for miles and hours. Just saw the topic, no desire to debate….your script is flawed.
>They can take a very long time to dissipate, which is perfectly normal.
Again, partially correct. Hot exhaust meet cold air, form ice crystals which dissipate once they reach the temperature of the upper atmosphere. These ice crystals DO NOT linger for hours. They DO NOT spread out for miles, meeting with other ice crystals and eventually forming a white blanket across the sky from horizon to horizon. The key to finding a scripted player is "atmospheric conditions". More important things to do, have a great day. And just for the record…you've no idea who you are conversing with, right?
