Chem trails
 

Today I was driving into Center harbor, there was not a cloud in the sky and we noticed several jet planes leaving a long trail of clouds that extended from one horizon to the other. We drove up to the top of Coe Hill and counted 10 planes crisscrossing the sky and leaving a chemical trail that lingered into a milky haze. It extended as far as the eye could see.......from Alton bay, to the White mountains. I googled it up and found some disturbing information.

IMHO, Chemtrails are just another gov't conspiracy theory. You'll find a LOT of hype and spin on the internet about this. There are also a lot of data that disproves these theories.
Contrails (condensation trails) are simply that, the byproduct of the plane engines. If the gov't were really 'spraying' us, why do it when it's bright and sunny, why not wait for night?????

Chemtrail conspiracy theory, is covered here as well.

They've Been Around Awhile!
 

HAHAHAHA
Listen to Coast to Coast AM overnights and you will be convinced that the government is killing us with Chem Trails, that shadow people invade our space, that time travel is possible...

Yep! Gotta give it to that AM talk radio!

Duckandcover!

Just because it's on the internet, that doesn't make it true... ;)

Ok,you guys....if you get abducted, don't blame me :eek::eek:
Actually,I'm not worried about a government plot......just surprized at those trails. Regular contrails dissipate a few hundred yards in back of the plane, but these stretched from horizon to horizon and didn't seem to go away.....didn't see any UFO's, though.

Just wear a tin foil hat, you'll be safe. Want to be extra safe, tinfoil underwear.

Again, I agree with you Sam. They are very different than the normal trails. They get much bigger and are in irregular patterns. They go up and down and crisscross each other. I think they are indeed something, I am just not sure what. I have been watching them for years. And they very often do appear on a very clear, sunny day.

The long drawn out trails that you see are the product of the planes emptying out there holding tanks. :laugh::laugh::laugh::laugh:

There are several reasons that contrails can become extended. There are also reasons that the contrails will converge, overlap, dip, etc. It is all in the atmosphere and how the upper air winds are blowing as well as how the vortices created by the aircraft interact with the condensation created.
You will also notice these contrails more at this time of year because the air is clearer and dryer.

Google, aircraft contrails and the crow instability effect.

Personally, I believe it is caused by the SL, allowing the full effects of GW and traffic by those d**n tourists! ;) Oh, I forgot the increased skydiving activity.

Very funny, Weekender....now that you mention it, I thought I heard some "plunk", plunk" sounds as they passed over.
Thanks for stickin' up for me tis....you may be the only person on the forum that thinks I'm sane:laugh:

Maybe it could be THIS ?!?

No, that's why the water is blue, so you can't see when it empties out.

I noticed an unusual amount here in Manchester also.Probably 12 or so.I think normally the upper air currents disperse the contrails so they don't last long.I surmized at the time that the winds at that elevation were probably non existant.

However, you see them in Fl. and it doesn't have to do with the time of year.

Are you serious? Do you actually believe this BS?

There are no government planes flying that spray chemicals into the air for any reason. The planes you see on such "irregular patterns" are mostly commercial airliners either coming from Europe over the Atlantic. What would you consider "regular patterns"? Do you know what the “regular patterns” are? Then how can you say what “irregular patterns” look like?

Contrails are of condensed water vapor made by the exhaust of aircraft engines. As the hot exhaust gases cool in the surrounding air they may precipitate a cloud of microscopic water droplets. If the air is cold enough, this trail will comprise tiny ice crystals.

The reason they get bigger is the wingtips of the plane create wingtip vortices, also know as wake turbulence which creates two columns of spinning air behind the airplane. This is what causes the contrails to spread out and dissipate. (The winds aloft help too)


When people see rainbows in the contrails they assume they are chemicals and that the government is to blame. Get a clue


Actually, you'll see more contrails when there is more upper atmosphere mositure. When the moist air is heated in the engine, then cools as it exits, the moisture is what freezes into ice crystals and becomes the contrail

Thank you Mr. Science
 

Good information, bad delivery.

Yes, I am very serious. I have watched the normal pattern of flights around my house and know normal. You may think what you want, I will think what I want. Years, ago you NEVER saw such trails.

Elaborating... I've heard that most of the moisture in a visible contrail is actually already in the atmosphere before the jet engine passes through. What happens is that the engines produce yet more water vapor as byproduct of combustion and if the local atmosphere at the flight level is already fairly saturated, the jet exhaust often adds just enough extra moisture to raise the dew point above the resulting atmospheric temperature as the mixture of local atmosphere and exhaust gasses mix and then cool.

Eventually, the moisture disperses into the surrounding, somewhat drier air just enough to no longer drop below the dew point and the contrail basically dries back up. How long this takes might be bit of a function of the aerodynamics of the plane and engine, which determines how well the exhaust gasses mixed into the local atmosphere. Mainly, however, it's a function of how close the atmosphere was to the dew point before the jet passed by, as well as what the prevailing winds aloft were after the plane passed by that determine how long the elevated moisture trail takes to dissipate, dropping the dew point again. Sometimes the contrails last a minute or so after the plane passes, (indicating a medium amount of pre-existing water vapor), sometimes there isn't any contrail at all, (indicating a "dry" atmosphere at that flight level), and sometimes they can last an hour or more (indicating a more closely "saturated" atmosphere. If the air is already completely saturated, you already have visible moisture, aka a cloud. :) )

Again, it depends mainly on how close the atmosphere already is to the dew point before the plane passes through the area (and at the altitudes typical of contrails, "dew" usually means ice crystals, which I suppose might last even a bit longer afterwards too.)

Without going into too much detail, I know what the air traffic patterns are in this area due to my job.

Years ago, there was not as much traffic flying.


And StephenB yes, what you said about contrail is also true, thanks for the added info.

I remember driving by a big, windowless building by the highway down in N*****, back when it was prominent fixture of the community and landscape. Now, of course, all the signs on the highway have been, um, sanitized, and not a public reference trace remains of that "facility."

I didn't realize that in this heightened-awareness kind of world, that the hush factor extended to staff now too. ;)

Two observations that complement the conversation here.

From time to time at work, I get to see air being evacuated from vacuum chambers and it is always amazing how much water vapor condenses out of the air during the pressure drop. A cloud bank forms in the chamber. My understanding is that the temperature drops from the pressure drop.

Another demonstration of the pressure drop causing condensation can be seen sometimes on the tip of an airplane wing where no combustion is going on. The pressure increase as the wing approaches changes to a pressure drop on the other side and you can see the vapor trail.

Well, Samiam, guess you and I are the only "kooks" on this forum. No one will convince me there is not a difference, so it will just have to be.

Guys - it's common knowledge that the Government stopped using planes to distribute chemicals to the population in the early 90's. All chemical distribution to the population has been moved to "organic" food farms (the illegals working these farms are given a secret asylum in exchange for mixing various chemicals into the manures and such they use on the organic food farms). Farm-raised fish is similarly tainted.

The planes continue to fly as a distraction. If and when any investigative study is ever done, you would find that all modern military planes have 100% inert exhaust gases as it relates to mind and population control substances.

See....I told you it was not the planes...lol

About this time of year, every year, the subject seems to pop up in various places. I think trfour nailed it with this link http://en.wikipedia.org/wiki/Contrail Take a look at the changes in the upper atmosphere this time of year, dew points are lower, temps are lower and the contrails last much longer. Maybe someone like Rose, who understands the atmosphere better than most of us, could give enlighten us. On clear days the upper atmosphere is dry and contrails persist.

Several years ago there were a lot of stories and letters to the editor in the Conway Daily Sun about contrails and one gentleman in particular was convinced it was a government plot.

Chemtrails are nothing an umbrella cannot fix.....:laugh:

AM radio: For the Defense
 

For those unfamiliar with the Coast to Coast AM program, it is a midnight-hours radio program whose earliest programming mixed the real science of Earth (and the Cosmos), with "para-psychology", other "para-sciences" and the pseudo-science of dreams and The Occult.

AM radio was "on the ropes" just 25 years ago: The resurgence of AM programming has found those of us "on the road" educated—if not wide-awake and entertained.

I learned of the "Moller Sky-Car" through the eariest C2C-AM version, and posted that information here at this forum. Today, the "Sky-Car" is being considered by the military. Also attempted by the military is an example of para-psychology: "remote-viewing". (Also a staple programming of "C2C-AM").

Predictably, "remote-viewing" was a complete flop and a complete waste of taxpayer money.

I credit "The Bruce Williams Show" with some of my better financial decision-making, "Money Talk" with other beneficial decisions and "The Kim Komando Show" with updates on consumer electronics. Her earliest advice has kept my "Windows Me" computer (Millennium) running fine these past eleven years!

Anyway, "Coast-to-Coast-AM" has morphed from their best days—with the steady hand of host Art Bell—into utter goofiness. They still include the occasional "real-world" story to keep that fraction of the listening audience who seek real knowledge. (A technique from psychology known as "random reward scheduling").

Their "Chem-Trails" programming has spawned several websites devoted to that conspiracy. (See also, "Aerosol Crimes"). :rolleye1:

C2C-AM once hosted an eminent American scientist, the late Dr. Stephen Jay Gould; however, most of their nuttiest guests have "Dr." in front of their names—to the extreme embarrassment to anyone who's worked for a degree—and a British accent. :rolleye2:

There's a reason "C2C-AM" is limited to the "wee hours", and must reach out across the entire planet with a half-dozen toll free telephone numbers! :laugh:

ETA:

A message to member Airwaves, and others unconcerned with media bias:

1) The new host, George Noory, was often vehemently anti-war; however, since the election—not a peep! :eek2:

2) Just now, I caught the last few minutes of today's C2C-AM show: they are revising the origins of Christianity. :rolleye1:

I used to listen to Coast to Coast sometimes when I couldn't sleep and when Art Bell hosted it. But I couldn't agree with you more as far as the way it is now-utterly goofy. I can't stand it and never listen to it. Shadow people and ghosts etc. they can't do anything else. It is true what you said though, it sounded crazy when you first heard it and then you find out it is indeed true or it is exactly what the gov. is doing. Too bad they lost Art Bell.
