Contrails or Chemtrails? You decide.

a reply to: tsurfer2000h

And yet even being back lit from the sun you still won't see dust coming from a contrail.

What 'dust'? Theres no 'dust' in contrails…

What has backlit got to do with it?

Once the particulates descend below a certain altitude the water vapor is no long visible. At that pointit helps to see the remaining 'exhaust' compounds and soot if they are backlit by the sun.

Water vapor is never visible.

I guess that stuff would be visible on takeoff too? When backlit?

Once condensed in sufficient quantities they are. Called water droplets they make up what are commonly referred to as clouds, Phage. In sufficient aggregation they fall out of the cloud and thats called rain…

One plane during takeoff? No.

The concentration from hundreds of passing planes in their flight corridor building all day off the west coast drifting inland?

Yah, its visible.

Yah, its visible.

Well yes, smog is visible. Dust falling from contrails? No.

Well according to you there is...

Iv'e argued about seeing the dust rain down from the contrails here on the west coast, its visible on the western skyline at times under the right conditions.

So which is it...

Either you have seen dust from contrails( which you stated you have argued about)

Or...

You are making things up...And I have a good guess which it is.

You mean the exhaust emissions go up? Where, into space?

Water droplets are not water vapor. Water vapor is invisible.
Your claim:

No, conditions have to be just right. Then anyone (who lives here) can see it, too.

Steam is water 'vapor'. You're playing semantics…

Your use of the term water vapor is inaccurate.

No one on ATS, you mean?

i used to point it out from the front yard of my brothers house at family gatherings. They all sawer it too, on those few occasions.

I know, Im' so underedumakated.

So where does the exhaust emissions from jet liners go?

Just to be clear you are talking about dust (your word)/particulates falling from a contrail.

No. Sorry I don't believe anyone has ever seen this. Including you. Sorry mate.

The water vapor either condenses or disperses (invisibly). The exhaust gasses disperse (invisibly). The particulates disperse, for the most part (due to their size, mostly sub micron) invisibly. They don't fall (unless entrained with subsiding air) any more than particulates produced by cars and factories do.
