Now wait a dog gone minute here. I thought cloud cover reflected solar energy back into space causing a cooling effect. Are we getting the old razzle dazzle from the woo-woo's? :wink: :) :D :roll: :lol:

Um... don't forget that clouds at night have the effect of blocking outbound terrestrial radiation! They do cause a slight warming effect over the course of an entire day. (Or were you kidding? Can't tell....) 8-[

I've been following the chemtrail stuff for a while, since I'm a meteorologist and find "cranky" stuff interesting. (Morbid curiosity?)
One thing I've noticed is that when the conspiracy folks say, "chemtrails," the response is, "CONtrails" (which is fine), but when the CFs say, "webby stuff falling from sky," no one responds to that (or they dismiss it). According to the manufacturers, chaff should come down with that kind of texture. Chaff is still used by the military, apparently for testing radars - but it has the unfortunate effect of confusing us. Sometimes, it's hard to tell the difference on weather radar between chaff and actual precipitation. And, of course, they don't tell us when they drop it! :roll:

Webby stuff falling from the sky is usually spider webs.

Commonly referred to by woo-woos as angel hair.

It's so typical of the Bush administration to waste government money spraying expensive mind-control chemicals way out over the Atlantic. Hello? Mr. Bush? You're constituents are farther to the West – that's where you need to spray the stuff. Sheesh.

This is exactly why I'm voting for Kerry. He will ensure that the chemicals are sprayed over populated areas where they are actually needed.

Vote Kerry in '04 – stop government waste of mind control chemicals.

Right, Tofu, I still say "they" are wasting an awful lot of chemtrail chemicals out over the Atlantic ocean. :lol: 8-[ :roll:

To any chemtrail buff who might read this, what happens is that when airplanes take off from a major airport and fly to another major airport, let’s say on a staggered take-off schedule of 1/2 hour or an hour apart, the first jet leaves a normal vapor trail which begins to drift to the East when there is a light Eastward high altitude wind. 1/2 hour later the next plane takes off and it leaves a normal vapor trail, and that trail begins to drift to the East. After several hours, if the trails persist, as they do on certain days, then that leaves a “streaked” pattern in the sky that makes it seem as if a “fleet” of airplanes all emitted the trails while flying side by side. But all it is, is a sequential series of normal Eastward drifting jet vapor trails.

Everybody sees a series of side-by side vapor trails from time to time, but nobody ever sees a fleet of jets flying side by side emitting all the trails at the same time.

When I was a kid, there weren’t any jet vapor trails because there weren’t any jets. But now there are thousands of jet vapor trails because there are thousands of jets.

A minor correction. It's a little misleading to call it a "jet vapor trail" because the type of engine really isn't relavent. If you have hot exaust contacting cold air, you will always have condensation. You can briefly make a contrail with just your breath on cold winter mornings.

A high bypass turbo fan such as that found on a modern airliner emits higher temperature exaust than a traditional piston engined plane, so it more readily creates a condensation trail. Also, jets tend to fly higher where the air is colder and less dense. However, piston-engined aircraft can create contrails. The air would have to be pretty cold though, but it is possible. There are a lot of WWII documentaries that show B-17 creating them.

I guess the real reason people didn't notice them before was that air travel was not as commonplace as it is now.

Not to mention, that when B-17s were flying overhead, the Germans had a bit more to worry about, than getting a Slight Head Cold ...

Yes, I understand that. I’ve seen old film of WW II prop bombers flying at high altitude giving out a vapor trail, but I don’t think we have any more prop bombers, and I’m not aware of any prop planes that fly at the high altitudes that generate vapor trails. I’ve never seen any low altitude vapor trails.

I don’t recall seeing any prop plane vapor trails in the ‘50s, but I began to see a lot of them when the 707 jet went on-line.

[Sam5]

When the jets of today don’t give off vapor trails at all, that’s when they are spraying clear invisible poisons on all of us. (cough, cough)

Coded vapor trails like this one:

Space Alien Vapor Trail (http://www.photovault.com/Link/Technology/Aviation_Commercial/show.asp?tg=TAFVolume18/TAFV18P01_12)

have been translated to mean, “Give up earth people. You are doomed!”

If I could just expand my statement a bit:

a. As I've already said, it's not entirely correct to use the word "jet" because even though you may not have seen prop planes creating them, it is certainly possible for props to do it.

b. it's also a little misleading to use the word vapor because that implies (to me at least) that the trail is exhaust gases. That isn't correct.

A condensation trail is nothing more than water. The water is already in the atmosphere before the plane flyes by. Because the engines of the plane are hot, they heat the air (and the water) and cause it to condense. That's all there is to it.

I just think the term "jet vapor trail" is wrong for those two reasons; it has nothing to do with jets, and it is condensation, not vapor.

So I guess I'm just hoping that we can stick with the term con trail instead. :)

Ack!!! :o

Most contrails are far above the freezing level, so it's frozen water, so we're discussing sublimation. But, since sublimation is ambiguous, let's go with condensation and evaporation anyway. :D At contrail level, only a tiny amount of water vapor is needed for condensation to occur, making a visible cloud. Exhaust from any engine adds moisture to the air. But, if the air is nearly saturated, anyway, just the lower pressure caused by the movement of the aircraft can cause condensation to occur - and it could take a while for it to evaporate. Heating the air actually reduces relative humidity.

I see jet vapor trails. Water vapor. White mist. All from jets. None from prop planes. :D

The engines also produce more than a pound of water per pound of fuel burned.

[LTC8K6]

Water vapor is invisible. High altitude contrails are ice crystals.

If I say “con trail” in the state where I live, the local people will think I’m talking about the trail of an escaped convict.

So white water vapor clouds are ice crystals, huh? Doesn't that make the clouds very heavy? What keeps them up in the air? When I fly through clouds in an airplane, why don’t I hear, “chip, bump, clunk, scrape, crack, zap, zing”?

[LTC8K6]

If you want to see contrails from a prop plane, watch Strategic Air Command with J..J...J...Jimmy Stewart!

Turboprops are jet engines anyway, aren't they? :D

[LTC8K6]

Water vapor remains invisible despite your misconceptions.

Clouds can be water droplets or ice crystals. The ice crystals are too small for your aircraft to be bothered by them.

High altitude contrails are made of ice crystals. When they disappear, they sublime right back to invisible water vapor. They are never liquid water.

Low altitude condensation trails are mist formed by low pressure areas formed in the wake of airplanes or race car rear wings.

[LTC8K6]

Why don't you hear a racket when you drive in the snow? :D

What keeps a cirrus cloud up in the air? :D

[Sam5]

I’ve got some pictures of a power plant that releases water vapor from a tall chimney. On some days the vapor is clear, but on other days it forms a big cloud, starting at about 1,000 feet. On some other days, it is clear up to about 2,000 to 3,000 feet, then a small white cloud forms over the power plant.

When ice crystals form in the high altitude where I live, we see sort of a “diffraction grating” effect in the sky. Also we see sun dogs sometimes.

[LTC8K6]

Cirrus clouds are ice crystals.

You won't always see the refraction effect. Conditions have to be just right to get the refraction effect. Lack of refraction certainly doesn't mean you aren't looking at ice crystals.

The chemmies think the refraction is because they are being sprayed with an oily substance. :D

[LTC8K6]

A rainbow is refraction by water droplets.

Thats because you are quite foolishly falling for the evil mind control. It is part of what makes chem trails so insideous! Those under the mind control of the chem trails believe that it is George Bush and the U.S. Government in charge of the nefarious plot! This is pure genius on the part of the man truely responsible for it..... that Evil Mastermind....Bill Gates! Think of it! Have you ever heard anyone say that the chemtrails are the work of Bill Gates? Of course not! What more proof do you NEED!?

I'm still voting for Bush, however, as he's targeting the island people and the Gulf Stream shipping traffic.

"mind control chemicals..." ROTFL

I really don't think we have enough dollars to fly that many military missions spraying so much mind control chemical that it's easily spotted via satellite...

When you see the entire roll, you can really see the dramatic change in such a short time. Also, that evening, even though I'd showered and washed my hair that morning, I noted an oily film on my hair, my arms, neck, legs - all exposed for those few minutes of photographing. It was very difficult to remove that film. The next day I had a slight burning sensation to those areas.

Have they been changing the method of spraying? Too many people catching on?

It's downright scary.

Dude, take a shower occaisionally to get rid of OILY HAIR.. Oh wait you allready did. :P

I'm sure people who spend their day's worring about chemtrails don't have much time to wash their hair though... =D> =D>

Planetside -

Nice picture of "cloud streets!" You don't even need aircraft to get those! :D

They're such a common occurrence in the southern Plains that you'd think they'd be taken for granted.

Just asking. Can a contrail make noise?
I told my brother about an interesting contrail article at www.oriononline.org/pages/om/03-5om/Rasmussen.html and he sent back the following reply from his apartment in San Paulo, Brazil.
"If you ever see any information on what might be called 'wake-trail collapse sounds' let me know. About 30 seconds or so after airplanes pass our apartment (they are only about 200 yards away, we can sometimes hear a wierd noise that comes out of nowhere, and sounds like a high-pitched wave successively crashing in on itself, moving quickly from left to right but without any real direction from where the sound is coming from. I think that the delay must be due to implosions into low-pressure areas in the wake trails."
That set me off on a little search, and you guys are my closest thing to help, now that he's got me wondering . . .

[Meteora]

Can a contrail make noise?

Nothing you could hear.

30 seconds is a long time after passage of an aircraft to hear anything from its passage (considering the distance involved). Do you have any other information that would help explain the source of the noise?

[Doe, John]

I've noticed this phenomena myself. I'll be walking across a parking lot, and hear something that sounds like a bottle rocket and seems to be coming from directly overhead. When I look up all I see is an empty sky.

I figured it was just Wonder Woman in her inivisible jet.

Just out of curiosity, how would the woo woo's explain the following 2 photo's ?

Seems you also get chems at airshows too.

Would they try to explain them or quietly shove them under the carpet ?

[Meteora]

I'll be walking across a parking lot, and hear something that sounds like a bottle rocket and seems to be coming from directly overhead. When I look up all I see is an empty sky.

Don't forget two things (maybe you didn't, but I can't tell from your post): First, jets move very fast - often close to the speed of sound. If you look directly at the sound source, you may be looking way behind the jet. Second, jets can be very difficult to see against the sky. On several occasions, I've looked for them for quite some time before locating them. A few times, I wasn't able to find the aircraft before it was clearly out of sight.
