Contrails dissipate quickly whereas chemtrails linger?

Contrails over London in 1944

Vapour trails left by British bombers on route to attack flying-bomb sites encircle the dome of St. Paul's Cathedral. London, 1944.

All those who passionately believe that "contrails dissipate quickly" whereas "chemtrails linger" and are deeply offended by the sceptical position that TNRA takes in regard to these claims, are free to "unlike" Truth News.

If, on the other hand, you would like to engage in rational debate, you're most welcome to do so.

However, please be advised that the information I have to impart may be shocking and difficult to grasp if you have been a "chemtrail alarmist" for a long time.

The often cited claim that "normal contrails dissipate quickly" is total bunkum.

There is not a shred of science to backup that claim.  Nothing, nada, zippo!

Those who promote this idea are simply repeating something they read on a web page without checking sources.


 

CONTRAIL SCIENCE

For a contrail to form, suitable conditions must occur immediately behind a jet engine in the expanding engine exhaust plume. A contrail will form if, as the exhaust gases cool and mix with surrounding air, the humidity becomes high enough (or, equivalently, the air temperature becomes low enough) for liquid water to condense on particles and form liquid droplets. If the local air is cold enough, these newly formed droplets then freeze and form ice particles that make up a contrail.

Because the basic processes are very well understood, contrail formation for a given aircraft flight can be accurately predicted if atmospheric temperature and humidity conditions are known.

After the initial formation of ice, a contrail evolves in one of two ways. If the humidity is low, the contrail will be short-lived. Newly formed ice particles will quickly evaporate. The resulting contrail will extend only a short distance behind the aircraft. If the humidity is high, the contrail will be persistent. Newly formed ice particles will continue to grow in size by taking water from the surrounding atmosphere. The resulting line-shaped contrail extends for large distances behind an aircraft. Persistent contrails can last for hours while growing to several kilometers in width and 200 to 400 meters in height. Contrails spread because of air turbulence created by the passage of aircraft, differences in wind speed along the flight track, and possibly through effects of solar heating.

Thus, the surrounding atmosphere’s conditions determine to a large extent whether or not a contrail will form after an aircraft’s passage, and how it evolves. Other factors that influence contrail formation include engine fuel efficiency, which affects the amount of heat and water emitted in the exhaust plume.

TNRA is informed by science and is not interested in propping up anyone's belief systems, and we don't apologise for that.

But, please, don't take it from me, speak to any meteorologist or any pilot and they'll tell you straight, that there is HUGE variation in the length and persistence of contrails. Sometimes they don't form at all, other times they form, but disspate quickly, other times they persist and spread out.

That's the facts folks, and it's been that way since planes first went up in the sky.

If you believe otherwise, I'm afraid you've been conned.

Forgive me if I seem rude or impatient on this topic, but every few months I come across a new wave of people who have been subjected to the same false propaganda about chemtrails, and I have to run the same arguments and cite the same articles over and over again. It does wear one's patience down.

Before making some kind of angry reply, I urge you to read this article and associated links. It's fairly detailed, and deals with most of the usual claims made by chemtrail alarmists.

Finally, let me qualify all this by saying that I do not doubt that geo-engineering programs exist, and that, indeed, some of the patented techniques discussed at international forums  include the creation of artificial cirrus cloud. Does this, however, entitle you to conclude that every spreading contrail you see is an example of such geo-engineering?

Think about it.

I don’t need radar because I can see the planes.

The problems occurring when spotting non-trailing planes - empty field myopia, saccadic masking, possibly light haze, planes appearing very small - do affect everyone.
Even pilots are warned about the dangers they create during flight.

Are you saying you are an exception and not affected by these problems?

Do you really think that everyday there are over a hundred jets in my little part of the South Burnett.

Looking at FR24, there are many, possibly 60-70 (varying, of course), because planes from/to Sydney and Brisbane do fly over the region. Run FR24 in time-warping mode to visualize the traffic during one day.

If you say you have counted hundred, I really would like to learn more about your methods of establishing that number. Even better - provide a series of images or a video.

By Josh on 2014 12 16 - 01:14:02

Cris,

I just counted the planes over South burnett for yesterday, Dec. 14th. I included only those which were actually crossing the region; you may be able to see many more from your place if they are trailing (usually around 60 miles in every direction).

The overall sum was 96. How many did you see?

Maximus
100?
Why do I see none or one on a particular day and 100 plus the next?
Come on MB. I’ve been watching this unfold for decades.
Are you going to tell be you know more accurately because you can’t see anything, have not been watching and ignorance is is more valid than observed., factual, real time, evidence?
Interesting hypothesis. Perhaps in a time of universal deception a thesis on the same would be acclaimed.

How many of the 100 were jets?
So there are 100 plus passenger jets going over my little bit of the world every day?
So there are perhaps 10,000 or so people on jets over my little piece of the world.
Where are they going?
What are they doing?
Not here mate.
Please forgive me for doubting you!
Do jet engines produce a contrail that is the entire width of the tail of the plane?
Coming from less than the width of the tail behind the jet.
I further doubt that I would see planes 60 miles away.
Particularly when being about 200 nautical Km from Brisbane and less from Mudjimba they would be into their decent.
Do you like breathing Aluminium, Barium and Strontium?
Ahh! There is the problem.

Janonymous outed himself again. I have flown Sydney - Brisbane and Brisbane - Sydney many tines over many decades and if an aircraft were to fly over the Burnett region during any such flight they would be so far off track it is not even funny. So, Janonymous, please get one of your QANTAS pilots to explain in detail how he could be so far off track, (about two hundred kilometres to the nearest town on the Burnett (about 108 nautical miles) NORTHWEST of Brisbane.
“Looking at FR24, there are many, possibly 60-70 (varying, of course), because planes from/to Sydney and Brisbane do fly over the region. Run FR24 in time-warping mode to visualize the traffic during one day.”
I suspect Janonymous is a whack-job rather than a shill.

I have repeatedly explained that. Why do you keep asking and then ignoring the answer?

How many of the 100 were jets?

All of the 96. There was one small plane flying IFR that I did not count. It’s unusual for small planes to have an ADS-B transponder equipped.

So there are 100 plus passenger jets going over my little bit of the world every day?

Nobody has claimed that. Of course it varies from day to day, and a big share of the traffic is freight planes.

Where are they going?

Click on individual planes in Flightradar 24 and you can see the flight details including destination.

Not here mate.

Are you saying Flightradar 24 is wrong and you are right? Can you elaborate?
Note that FR 24 is based on many independent volunteers who receive ADS-B data directly from the planes and upload it.

Have a look for yourself, by all means! In my last post I provided a direct link to the beginning of the recorded day.
How much easier do you need it to be? You can see the links in my posts, right?

I further doubt that I would see planes 60 miles away.

Yes, probably not the planes but you’ll see the contrails.
Other people have taken on the task of finding out the specifics. You have the given contrail height of about six miles, so with simple trigonometry you can determine the approximate distance from the viewing angle over the horizon.

Five degrees means 68 miles, roughly 110 km - in every direction. South Burnett is grossly 80 km wide and 120 km long, so your field of view is bigger than the area of the region.

Leonard Clampett,

I have flown Sydney - Brisbane and Brisbane - Sydney many tines

Huh? Did anybody talk about that route?

I said that planes from Sydney and to Sydney as well as planes from Brisbane and to Brisbane are flying over the region.

Earlier I have stated (referring to Queensland):

“All the traffic between Shanghai, Beijing in the North-West and Sydney in the Sout-East is going over it, as well as the Brisbane - Singapore route. Among the traffic are many cargo flights which shouldn’t come as a surprise. Then add all those continental connections.”

Here is a direct link to the enroute vector map centered over Brisbane. Drag it to South Burnett - as I said, fairly busy.

Janonymous seems not to be able to understand that which he writes. BTW Janonymous, you did not “say”, you “wrote” the following. Perhaps English is not your first language, but you seem to try hard with it to demonstrate your odd views. You WROTE the following;

“Looking at FR24, there are many, possibly 60-70 (varying, of course), because planes from/to Sydney and Brisbane do fly over the region. Run FR24 in time-warping mode to visualize the traffic during one day.”

.

This means aircraft from/to Sydney and Brisbane. There is no mention of any other geographical locations so it is demonstrable that you refer to those two cities. It means aircraft flying between the two cities. If you really knew anything about that which you claim, you would know that aircraft that fly over the Burnett are not those between Sydney and many other places. Look at the maps. look at the high and low level RNC’s. Wake up. If you meant aircraft arriving at, and departing from, Sydney and Brisbane for other locations you would have written so.

By Leonard Clampett on 2014 12 18 - 07:58:26

Janonymous, if you knew anything at all, you would know that the Skyvector aeronautical charts you give reference to are simply charts of airways and no indication of any traffic whatsoever.

Pretty busy here.
Looked at the link late last night.
If there were planes on those routes I would have seen very few as nearly all of the routes don’t come close enough to me.
Maximus, you are not omniscient.
You are clueless.
By the way I I still don’t have an answer for when there are 3 or more abreast?????
What about the ones that intersect those paths….only a few of which go near me?????
What about the stop start ones?
And the ones that make curvy border around an approaching weather front?
Or the giant circle that I took photos of?
Just because the lap dog news can pump out NWO propaganda unopposed because they won’t print evidence to the contrary doesn’t mean you will get away with it.
Do you need hearing aids?
VERY FEW JETS UP HERE UNLESS THERE IS IMMANENT RAIN!!!

he must really struggle with simple day to day tasks.. honestly.. that is another example of when he accussed me of making threats, then denied he wrote that, then wanted me to show him precisely where he did, and when shown, simply ignores all reference to it..  pretends it didnt happen at all.. unbelievable really - if he is the best answer to prove that chemtrails dont exist, they really are struggling.. 

he thinks proving a point, obviously, is simply banging away at the keyboard and hitting submit, with no consideration to rhyme or reason.. relevence, consistency, logic or common sense.

he wont / cant even answer simple questions.. incapable of providing a yes or no answer to a simple question. he feels his inconsistencies, lies, qualifications, credibility, have no relevence to anything so long as he keeps the babble going on and on.. he is doing a good job.

I suspect Janonymous is a whack-job rather than a shill.

you might be right there, it would be almost impossible for a shill to pretend to be so stupid.. and in most instances, id feel a little bit of pity..  but i dont in this case, he needs medication or something, he is obviously in a lot of misery..

By the way I I still don’t have an answer for when there are 3 or more abreast?????

you dont get answers from josh anonymous.. its beyond his capabilities, you will get a whole heap of incomprehensible bluff and bluster though..

i usually try to make it easy for the poor sap, just asking simple yes or no questions, or those requiring a one word answer..  but they seem to be the ones he struggles with the most? - he really is an enigma.. he should donate his body to science, and i dont think he should wait till he dies either..

By Andrew Adams on 2014 12 18 - 08:45:51

Leonard Clampett is correct if he states that airway charts are no direct indication of actual traffic.

However it shows that there are designated routes over South Burnett. It’s not an area where air traffic is unusual.

For the actual traffic consult Flightradar 24 over the South Burnett region.

Regarding the semantics of “from/to Sydney and Brisbane” let me clearly state that I never had the route between Sydney and Brisbane in mind. This might have been more clear to people following the discussion with Cris.

The bottom line and the relevant point is that there is just no evidence for days with “only one jet” over South Burnett. Flight tracking shows clearly that there is constant traffic over the region. Show me a day with only five jets over South Burnett on Flightradar 24 - even limited to the daylight period - and I will be convinced.

The statement of Cris (“We are lucky to get 1 jet a day visible here normally”) can indeed only refer to the visibility with bare eyes on a non-trail day, not the actual traffic, as explained extensively and repeatedly.

Regarding the “3 or more abreast” situation that Cris referred to, I quote my reply from the first time this was brought up:

Next time you see three planes abreast, or circles, or grids - grab a camera and take a picture. Otherwise it’s hard to say what you saw. May have been normal traffic where the many routes are bound to intersect at some points, or circling in holding positions, or military exercises.

Without seeing pictures, it’s just speculation.

I can add now that I have observed several situations on Flightradar where three planes were close together (vertically separated of course), going in the same direction. Why should that be unusual?

RECLAIM AUSTRALIA IS DOOMED

Although I agree with many of their ideas, the forces reigned against RAM are too great, violent, statist and reactionary for them to remain a non-political, broad based, multi-ethnic, community protest group for much longer. The Left and their Antifa nihilist fellow travelers are already pushing them towards the extreme Right, by calling them racists and Islamophobes and so on. Whilst the extreme Right have aligned themselves with RAM. With fascists of the Left and Right pressuring them they will not be able to remain beyond the Left-Right divide and will inevitably move to the Right - the extreme Right. Which is already happening. A development which will alienate decent Australians of all ethnic backgrounds many of whom currently support them. 

The RAM leadership have already established open alliances with the Patriotic Front (the ape in the photograph is a Patriot Front supporter at a recent Richmond demonstration) Australia First and Golden Dawn, a Greek neo-Nazi party. Members of these collectivist groups are currently attending RAM demonstrations all over Australia.

There is a real need in Australia to establish a political movement beyond the Left-Right divide and their vested interests, a movement that questions the current direction Australia is heading i.e. the direction the Left/Right and their extremes would like to take it; that questions the efficacy of state sponsored multiculturalism, as opposed to a proper, non-discriminatory immigration policy; that questions the validity of political correctness; that is politically neutral, anti-war and pro environment; that is opposed to all collectivists ideologies (fascisms of the Left and Right); that would dismantle the power pyramids of corporations and banks and their ability to impact on government; that would dissolve all anti-terror laws and all laws that impose on the rights and freedom of the individual and the people.

I second Keith’s assertion that Mike Holt from Restore Australia is very much a fake.  He bangs on about Halaal being a scam and money maker for Islam (and no I don’t support Halaal whatsoever), but makes excuses for its counterpart Kosher as being a somehow legitimate.  Double standards?  When I confronted him about this fact he went off on a convoluted tirade about Israel being some sort of “Bastion of Democracy” in the middle east…Really!, I will leave that one up to the readers to decide on.  I found that MH came across as disingenuous to say the least.

Without doubt, TNR is one of the best, if not the best alternative news source on the net. Which doesn’t mean Herewood is always right. His job, I believe, is to present the facts as he sees them as an objectively as possible, without fear or favor.  For this, he has my respect and support. But I believe he needs to be careful and to think a little deeper about the problems of “racism,” in Australia. He has labelled the Reclaim Australia Movement as racist. I’m wondering if his objectivity is a little weak on this point, a little without foundation.

Of course all political movements have its fringe groups and individuals. We make a distinction between, for example, a Muslim and a fundamentalist Muslim (Islamist), and by so doing we don’t claim that all Muslims are blood thirsty fanatics. If its good for the Muslims, then its good for RAM, which is bound to attract a few lunatics and real racists. But to brand the entire movement as “racist” is wrong; it is the same ploy that is used by the mainstream media and its left-wing, establishment Marxist boot boys.

One of the first things I noticed when i attended a RAM rally recently were the amount of non-white people in attendance, including Aboriginals. In fact the main banner of RAM contains an Australian flag and an Aboriginal flag. Speakers at their rallies have included Jews, Arabs, Indians, Aboriginals, Chinese and so on. What does this tell you? Is this really a fascist-Nazi-racist movement whose stated aim are the eradication and exclusion of other cultures, in place of some sort of Aussie white Reich, or is this just propaganda that is being propagated by the left for their own political interests. Consequently, we all know where the culmination of their politics have led, historically speaking, which are to the imposition of terror and dictatorships.

We can be thankful for small mercies, in terms of the Left, which today mostly tends to attract collectivists, establishmentarians and the privileged sons and daughters of the upper bourgeoisie, who seems to share one thing in common, nativity….

Mike Holt from Restore Australia is very much a fake.  He hasn’t even been citizen for but a few years.  But, he makes out like he was born there.  ALSO - this guy spent 30 years in Thailand working shady businesses.  I would wager that his primary purpose in being an activist is that he wants to make money off selling merchandise.

good to see you putting out some new shows heraward

freely the banana girl is to a certain extent a troll, as is her boyfriend durian rider. they have been trolling the fitness community on youtube for some time… and yes they are extreme but they are also trolls. They use their trolling to spread their message. currently, another dude called vegangains is trolling the fitness community as well.

i am a vegetarian, and it was seeing this documentary on the pork industry that started me on the vegetarian path. for anyone interested, its pretty off the charts disturbing and its australian as well. its pretty much made by dudes breaking into pork farms and filming what they find

https://www.youtube.com/watch?v=KArL5YjaL5U

Would the world be better if people cared where their food came from? probably, they might then care about other things too

do you become a better person if you dont eat meat? i feel like a better person mainly because animals aren’t being hurt because of me. i dont feel humans have to eat meat really… or at least not much. How can you watch that documentary on pork, know that that is pretty much whats going on and turn a blind eye to it? I think its basic empathy and just saying well ‘i like bacon so yeah’ is in my opinion wrong and i can see freleys point of view to an extent. In my opinion, at least these people believe in something. i see my money as my vote, henceforth im ethical as to what i do with it. free range eggs became mainstream for exactly this reason… although im pretty sure woolies and coles lobbied the state to change the definition of the word ‘free range’ at some point. I dont eat beef because the amount of resources that go into growing a cow are pretty crazy. Think about how much grass that cow needs to eat before it is harvested and how much space it requires. think of how many vegies you could grow in the same space with the same amount of water. lamb? comon, think about what your doing here… but that being said i think most vegans are total loons. People like freeley should be advocating for the destruction of lions and tigers, as lions and tigers murder other animals in truly horrific style. if we humans are smart enough to not harm animals, then we should be stopping the animals that harm other animals from existing. Freeley also kills birds when she flies in aeroplanes so she is a hypocrite.

feminism is one of the biggest problems in society today and although there is some valid historical basis to it, the liberation of the human female from their biology is in my opinion largely a product of the technological advance of humans. sufferagettes where never machine gunned on the streets, unlike the men that where drafted and sent off to war to die just a few years earlier. as technology has advanced, women have advanced as well, however now its going way too far and is pretty blatantly anti male in many respects. i view feminism in its modern context as a tool of the social marxists that really isnt doing society a great deal of good at this time. its screwing up gender dynamics and is wrecking women and men for each other. i see it as low frequency, lowest common denominator idiocy, just like a lot of the the race baiting ‘is this racist’ stuff getting around that is being perpetuated pretty much as a distraction, divide and conquer strategy by the power elite. idiots love this kind of bicker and beef… it would be funny if it wasn’t so serious

anyway

I agree with steven friar. gods a maniac

Almost two months since the last broadcast! How the hell can you expect people to donate when you don’t broadcast? Looks like the ship of truth has sprung a leak. This broadcast has been part of my life almost since its inception…it is one of the few alternative news sources that hasn’t gone off the deep end, by dilution credible information with crap e.g. Fairdinkum Radio and Info Wars…Pittard started FR with some incredibly interesting material, but then he flipped…Today he sounds like a fundamentalist preacher, the Christian equivalent to a Fanatical Islamist. As an atheist, I think he’s really ###### up a potentially good show. As for Info Wars, all they would have to do to improve is dump Alex Jones, what a shit-for-brains. I reckon Jones and Pittard are allowed to proliferate, because they’re so stupid and harmless. I suppose they have some entertainment value, and along with David Icke are living examples of how low the alternative media has sunk. Truth News Radio is, or should I say was, way ahead of them all ahead of them all in terms of credibility How sad that its come to this.
