"Chemtrails?" Nope. just contrails

There's a movement among those who are even more distrustful of our government than most of us to delare said government is engaged in some kind of nefarious experiment with aircraft spraying chemical or biological agents seen in the air as "chemtrails." What "chemtrails" people forget, though (aside from the fact that this would have to be one of those huge conpiracies where no one ever talks) is that ordinary contrails can take a wide variety of appearances, including some that are quite weird at first glance. Winds aloft (or lack of them), ice crystals in the atmosphere, and other factors can make a contrail linger long after you'd expect it to dissipate and look anything but normal. Here's just a sample.
