Chemtrails... I made a few in my aviation career. We generally call it burnt kerosene, generating dihydrogen monoxide and carbon dioxide. Put that dihydrogen monoxide up at say 30,000 ft or so, and that lovely trail of burnt hydrocarbons condenses in the near -37°C rarefied air (depending on lots of variables, but you get my drift). We then call it either a vapour trail or condensation trail.

Cirrus cloud. Yes, indeed another chemical. It's called super chilled Dihydrogen monoxide. REALLY dangerous stuff. Too much, you drown. Too little, you dehydrate and die. Lower down in the atmosphere, we call it rain. Really really bad juju.

In fact, some dihydrogen monoxide just stated falling here from a sky covered in chemtrails.

You have more to worry taking pictures out of car windows than from these horrible chemtrails.

Hmmm, we are doomed - lots more chemtrail precipitation this morning
