The pine beetle and west nile seem to make the most sense. But I gotta go with Nitramjr. He's a pilot. But you know what? I live under the approach to YVR. No con-trails around here. I see them higher up, at cruising altitude, or climbing away from YVR.

 

contrails aren't new, thats actually one of the things that the sites that talk about mistakes in movies like to point out in the old westerns, like the Clint Eastwood spaghetti westerns, or the John Wayne movies. there are contrails in the sky in what the movie is depicting as the mid to late 1800s.

As soon as I saw the title of this thread I just knew someone has been staying up late listening to Coast to Coast AM with George Noory.

Now I will say I am not going to completely dismiss the theory. no the pilots talking isn't enough to convince me 100% because I have actually read government released documents talking about spreading reflective particles at high altitude to reduce global warming that is they claim is increased because we have done such a good job of reducing particulate emissions in the past 30yrs. And the same article discussed the not only experimentation of this but how they had and were actually putting it into affect (this was during the mid 90s) and considering that one of the conspiracy theorists ideas is that it could be particles being released in an attempt to reduce global warming and that coresponds directly with the government released information, and the fact that the idea of it even carries a US patent, (United States Patent 5,003,186Chang , et al. March 26, 1991 Stratospheric Welsbach seeding for reduction of global warming ) I kinda got to put a little faith in that at least some of it probably IS some type of "chemtrail"

 

The truth probably lies somewhere in the middle. For those who prefer not to entertain any possibility of conspiracy, I offer...Flouridation!

 

Um Jet engine Exhaust can get to temperatures as high as 2500C and yes that um will burn you, really bad

 

And why was my Post Deleted ?

 

Those were caused by UFO's, man. George Noory said so.

 

Well, I did some digging and I learned something today, never knew the scope of this Contrails debate, seems it's quite the issue for some. The FAA site seemed to offer me a reasonable explanation of this phenomena, as well did a few other METAR and weather data sites.

I'm finding myself leaning towards the reality of this being no conspiracy but an unnatural cloud formation caused by exhaust by-products in the upper atmosphere..

But I'm still open to the possiblity of weather manipulation in the upper atmosphere , as there has been some talk of experiments done in the past. What the grounds for the experiment was or is, remains unknown to me. Tesla, Schuman and HAARP seem to have something to do with the experiments from what I hear.

I've concluded that it seems rational to me to assume this is a natural \ manmade occurrence as most of the evidence suggests, and somewhat irrational to assume a conspiracy at this point, it lacks substance and offers no reasonable explanation to me.

Thanks for the posts, I in fact learned something today that I have never really thought about in any great detail.

ditto to that, one day this will be solved, so were not all trying to guess what it could be. maybe its binladen, you know the guy that lives in a cave that pulled off 9-11

 

Its already been reasonably explained... Expect those who utter "I reject your reality, and substitute my own"

As far as weather manipulation that has been done in the past and at times is ongoing.

Hardly tinfoil hats and X-files materials though.

 

Ever stood behind a jet as it was taxiing? I have. It is hot, but NOT that hot. Now, if you are talking about inside the engine, prior to it exiting behind the aircraft, then it might be hotter, but the exhaust of a jet is not hot enough to burn your skin off. It might get hot enough that you are looking to get away from it, but it won't burn you.

 

I have to add something that is slightly off topic of this thread but funny and does relate to at least where a lot of this thread comes from.

I was listening to Coast to coast a few years ago and Noory had a guest on that was discussing some conspiracy or another (really don't even remember what the topic was to be honest) and about 20 minutes into the show George pipes up with "you know I think your too far out to be credible" and hung up on the guy then saying well I guess we now have about 2-1/2 hrs of open line time to fill. All I can say is if your too far out for that program that Noory thinks your a nut job and hangs up on you, then your really need help.

 

At break away thrust the B737-100 with JT8 D-17 engines will produce roughly 150*F ( 66*C) @ 3.3ft ' from rear of aircraft, now @ 60 'ft that is reduced to 100*F (38*C) Take-off Temps reach 200F* @ 3.3"ft and @ 255'ft are reduced to 100*F

Now at the compressor outlet you can expect 1000*F and at discharge from engine about 850*F, reheat (afterburn) will get up to 2100*F + on some engines because of recuperator . so with knowing that, standing a fair distance from rear of plane would give a nice warm breeze, not enough to cook skin.

I'm with stu37d on that point

 

There's allot of talk about Chems I talked to my friend who use to work on the B1 lancer at Dyess AFB in Texas, I asked him about the fuel where did it come from and had he ever seen it off loaded, he said we got it from the same trucks that bring fuel to any gas station.
At my last job when I worked at Penske I was baby sitting as we called it the guys who dumped our fuel and I remember him saying that once in awhile he would dump jet fuel at Cannon now and then and then he would dump some other type of fuel that they called goop he'd get it at the same fuel depots where all the other fuels come from. So when is this Mysterious chemical getting mixed at, what is the Chems in Chem trails why are they doing it. if you ask me its a bunch of scared to death paranoid people looking for some thing to be scared of.
No one can give a valid reason of why? its all ways the same old carbon copy answer of the Govts trying to kill us all or turn us in to Zombie's. Personally I'm more scared of the Tv, thats the only thing turning the masses in to Zombies..

 

Nomad I said I don't completely dismiss them and DID post a reason why including the US patent number for the application listed. Now I don't believe all of it either but I do have a tendency to believe there is some basis of truth to a lot of conspiracy theories and the basis I can see is the one I posted earlier about putting particulates into the atmosphere to reduce global warming or at least experimenting with it. (really wish they would stop trying to destroy the economy and playing around with stuff that they can't even prove exists but thats another thread)
Now nothing in that is paranoid schizophrenia about the government trying to kill us.

Sheesh I wish some people weren't so willing to dismiss stuff because a fringe element come up with some wacko stuff.

I also don't believe it's chemicals so much but sorry I seriously doubt that ALL those "contrails" are a naturally accurance of jet exhaust at high altitude. and the lame excuses of why some of them last for hours doesn't fly either (even clouds have to move and regenerate or they dissipate so how can something as thin and fragile as the exhaust plumb of a jet engine stay in the same area for hours on end? answer it can't physically)

Oh and no one that I know of has ever said that the chemicals are being sprayed by burning them in the jet engine first so the fuel issue doesn't prove that chemtrails don't exist but rather makes it look even more like a cover up to come up with a cover story for something that isn't even being questioned.

 

Ok here's where I'm at. I think people believe what they want to believe when it makes no sense at all(mellencamp quote) if what were talking about here makes no sense to you, then you probably jump to an assumption myself included, now depending on what side of the line your on, that's where you'll probably first go with it, meaning if your all trusting in your goverment and feel they always have good intentions for you and don't just have their own agenda, then you'll proabaly look for a resonable explaination and go with that and carry on, but if your like me and don't really trust a thing that they say or do, then you might wonder what might they be up to now,(beening more sceptical I guess) .Then I'm searching for a little more concrete evidence, to relieve my suspicions, I can't go with oh! that sounds reasonable, because at this piont were all spectulating, including myself, I'm not searching for an answer that fits my suspicion, but one that will disolve it, were all searching for the truth, what ever that might be.
