Oh it's called Contrails, I didn't know that. I found lot's of info on it
on the web. Thanks.

Just beware of the paranoid lunatics who talk about "chemtrails".

Well, you know... it is, after all, a *very* dangerous chemical:

Dihydrogen Monoxide (DHMO) -- someone has posted a MSDS (material safety
data sheet) on it:

http://www.dhmo.org/msdsdhmo.html

So...



Best part was the time where city hall in a town in the U.S. actually
passed a law banning DHMO. It stood in force for a day before the very
red-faced city council repealed that ban.

I do, however, have great respect for DHMO in its various forms since it
can cause real problems for GA pilots. :-)

(Alternative theory: contrails were invented to give the chemtrail kooks
something to do in their copious spare time. /tongue-in-cheek)

Note to AliR: I'm just kidding in this post. Not poking fun at your
serious inquiry, which has gotten a number of great responses. I'm just
poking fun in passing at the chemtrail kooks.
