Reply #145: You can't watch a "chemtrail" for hours. [View All]

[Silverhair]

The upper air moves, usually at around a hundred miles an hour, or better. So in an hour, a contrail is going to be about a hundred miles away. And you claim that you have seen them persist for hours. Then you are claiming to have watched them as they drifted hundreds of miles away.

If you would actually learn some meteorology, you wouldn't embarrass yourself.

Man made clouds can persist for exactly the same reasons that natural clouds persist. Once the contrail is out of the engine, it is ice crystals and subject to exactly the same natural forces that clouds are. Sometimes they will sublimate quickly, and sometime they won't at all.
