Some shills here tink we are stuid. Contrails never develop so widely into making it a cloud and they are never long. NEVER! You shilloids either are too young and don't remember what normal contrails look like, or you are just a disinformer. Quoting: Anonymous Coward 1516837
You ARE stupid if you actually believe you can see a trail from the ground and "know" the trail is full of chemicals just by the way it looks from the ground.
I'm 46 years old and have see these trails since I was a toddler...when my father first pointed them out to me and explained them.
I'm no "disinformer". I'm actually educated in the subjects that explain the trails. Ask ANY atmospheric scientist on the entire PLANT what these trails are...and you'll get the same answer...Why? Because they are all in on it?!?! No, because the trails are contrails.
Just because where YOU grew up there weren't a lot of high efficiency jet engines bringing the saturation past supersaturation overhead...doesn't mean I didn't see them over the Boston suburbs for over the past 40 years!
There are MANY variables that have changed over the years...engine efficiency, cruising altitudes, air routes, more airports and flights added. For you to ASSUME that these things don't matter (and you actually understand these things) is fucking IGNORANT!!!
