The chemtrails hoax is a good conspiracy fantasy because of the security surrounding aircraft and lack of knowledge about aircraft most people lack. People don't know enough to realize they are sounding like morons when they push this stuff.
The people that push chemtrail
are too aeronautically stupid to even understand the very basics of what they are seeing.
Its cold up there. The two byproducts of burning jet fuel (which is, basically, diesel fuel) are CO2 (carbon dioxide) and H2O (water). You can't see the CO2 but the water, in the form of steam. ...and since its a long ways away and up in the sunshine, it looks massive and thick.
I figure chemtrails are a good way to detect the morons in our society. Well, the morons and the easily deluded.
I'm sure we'll get some morons in here whining about how were "disinfo" agents or some such
but I don't care. There does not seem to be any validity to the chemtrail delusions and we need to spend our time on something that has at least a few shreds of facts.
