But in the end, its all just light vapor, right?
That doesnt explain how they not only do not dissipate, but expand and actually grow thicker as they expand, turning sunny days into overcast days... lost count of how many times I've watched it happen.
You start seeing crisscrossing lines on a bright sunny morning, evenly spaced lines in grid or x patterns... next thing you know its a foggy haze that hangs around all day.
Thats not the behavior of burnt up jet fuel.
