http://www.boeing.com/commercial/aeromagazine/aero_14/vortices.pdf Not sure what this means, but it's definately interesting reading, and a nice photo of a plane leaving a lovely gigantic contrail..

I read a little further into this, and from what I can tell, if they implemented this, after say 5-10 nautical miles, it could cause the contrail to completely break up..Hmm.

I don't think the 'flaplets' are designed to break up the contrails from the engines, but merely to break up the vortices (which may or may not even be visible) from the wings.Obviously, wake turbulence iw a big issue now, what with that Airbus going down in New York back on October. I'll check into this further tomorrow and see if I can raise someone rom Seattle. I'll pass along whatever information I have.

Please allow me to clarify something....as I said before, my background, is that I am an airline pilot....The vortices they speak of otherwise known as wingtip vorticies or "wake turbulence" is something completely different than a contrail. A wingtip vortice is the result of the high pressure underneath a wing mixing with the low pressure above the wing and creating a horizontal tornado, if you will.....these vortices are quite strong from larger aircraft and can pose a danger to other smaller aircraft encountering them especially during take off and landing (the are strongest when the aircraft producing them is slow and heavy)....You cannot see a wingtip vortice unless it swirls through something like dust, fog, or clouds. The reason Boeing is studying ways to break up these vortices is because Air Traffic Control has minumum distances behind these larger aircraft that they must maintain in order for them to put another smaller aircraft behind them. If they came up with something to reduce these vortices, they could reduce that distance, therefore allowing more takeoffs and landings in a period of time, therefore reducing congestion at airports. A contrail, however is the result of the hot exhaust of an engine cooling and condensing, forming a long, miniature cloud on particles in the air when conditions support it. There is nothing inherently dangerous about a legitimate contrail for Boeing to want to study. I just wanted to clarify the large difference between the two.

...If you're really an airline pilot, then Im quite positive then you know something unusual is occuring in the area of aircraft emmisions,and if you're not,then your not really an airline pilotor you are intentionally lying... then one must wonder what your purpose is here in posting in this forum...It is obvious to me that the original poster in this thread never attempted to claim contrails and wingtip vortices were the same thing,but wanted to know if reasearch in this field could relate to chemtrail dissapation. ... your words were intended to make the writer look stupid.I have seen(and personally experienced)this method of discrediting someone.It' a lowlife trick in my book.Incidently, i hope youre not an airline pilot, I know I wouldnt knowingly fly with anyone who claimed he was a pilot and chemtrails dont exist..I would know already you were a liar

Bob, B.....If you would read SCADJ's post, he said "contrails" not chemtrails.....and also, Duncan Kunz had essentially the same response that I did. A friend of mine told me about this message board. I have 11 years of flying experience, 4 of which are with an airline. While I don't necessarily beleive in the existence of chemtrails, I find this board interesting to read (I read and subscribe to lots of message boards). I will never (and never have) given a smartassed or flaming response. My post, as was Duncan Kunz's post, was to clarify what seemed to be a misunderstanding on SCAD's part. That is all. You beleive chemtrails exist. That's fine, it's your opinion, you're entitled to it, and I respect that. I'm not trying to change anyone's mind.

Dear BobB:You say that you "...would not knowingly fly fly with anyone who claimed he was a pilot and chemtrails dont exist..I would know already you were a liar." We each are entitled to our own opinions, of course. However, my job takes me in contact with a lot of pilots, many of whom are my colleagues at work; and my next-door neighbor drives 737s for Alaska Airlines in addition to a stint in the Air Force Reserve. No pilot I have talked to believes that chemtrails, as you define them, exist. Most of them hadn't even heard of such a phenomenon and either shake their head or start to laugh when I mentioned the controversy. Now maybe they all know that there are chemtrails and they're all lying to me. Or maybe E. coli and I are lying to you, and there really is a plot with a half-million or so folks in on it. That's for you to decide; I'm not going to tell you what to think. But if you are serious about avoiding commercial flights unless they're crewed by pilots who accept that chemtrails exist, you might want to invest in a detailed operations schedule for Greyhound -- 'cause you won!t be doing much flying!

I respect your opinion,you ar entitled to it, but it is in obvious error . I have spoken to airforce pilots here at Barksdale who claim "arial obscuration" is a daily occurance, and they are being told to catagoricaly deny it.The fact that Reagan replaced the Air trafic controllers with government replacements back during the 80s in a strike situation is relavant to what is occuring today!!!They do not even know what they are doing themselves, that are not being told straight facts about what they are spraying and why..If you go to the photo archives,Duncan, you will see a picture I obtained of a c-141 spraying, a photo taken by an airforce reservist {from the cargo bay door}

Is this the photo of which you are speaking? http://www.chemtrailcentral.com/cgi-bin/db-search.cgi?template=img-detail&dbname=img&key2=914&action=searchdbdisplay I'm not going to tell you that, "No, it's not chemtrails, dammit!"....What I will tell you is what I see about the picture using my first-hand knowledge of aviation. I don't know if it's a C-141 or not, but it it is some transport with a rear ramp door. Let's just say that it is though for the sake of arguement. I see 3 other aircraft trailing this C-141. I would identify them as C-130 Hercules aircraft. A C141 is a 4 engine JET transport with a cruising speed of somewhere around 450-500 knots. A C-130 is a 4 engine TURBOPROP transport with a cruising speed of around 250 knots. For the C-141 to be able to safely slow down to lower it's ramp in flight and to not leave the C-130's in the dust, it has to extend it's wing flaps to safely maintain that lower speed. A lot of times in high humidity, you will see these tight, mini-vortices coming off aircraft's flaps (hang around an airport on a humid, misty or even rainy day and you'll see what I'm talking about). That to me looks like why the trails are not atomizing into the air as a sprayed liquid would. To me, a sprayed liquid would spread out into the airflow and become a much wider trail. That is just what I see.

.."I have spoken to airforce pilots here at Barksdale who claim "arial obscuration" is a daily occurance, and they are being told to catagoricaly deny it."<<If these AF pilots are being told not to speak about it, versus "deny it" by their superiors, it would be classified. Why would they be sharing classified information with you? If it's unclassified, why aren't they sharing it with higher-ups on the "chemtrail" chain, like Thomas or Carnicom or better yet, writing to Jeff Rense? The photo you obtained has been on the net as proof of "chemtrail spraying" since the story began, and debunked long ago. http://pub31.ezboard.com/fcontrailsandchemtrails22884frm1.showMessage?topicID=392.topic

Kids, Kids, Hold on now. I've had it with all this bullshit chemtrails?, contrails? air vortices? Request an e-mail from me, and I'll reply with a very short video (best viewed with media player at 200% zoom) that depicts an aircraft turning off, then on, then off, then on once again all in midflight it's "CHEMTRAIL"? "CONTRAIL"? "AIR VORTICES"? or whatever the hell you want to call them. I was waiting to release this video in it's full length form on the net and still intend to do so, but it appears I might stop some delusional thinking (for some of you, you figure out who you are) from even taking place. What can you lose by viewing? BTW...If Boeing is successful in creating "flaps" to quickly disperse "CHEMTRAIL" visibilty, what will all us conspiracy theorists find to do with our time? Just a thought........

Dear Phantom911:Two comments: First, please send me the video, but do not send it to work, since I don't have the video player on my office puter. My home e-mail is duncankunz@cox.net Second, you said, "...If Boeing is successful in creating "flaps" to quickly disperse "CHEMTRAIL" visibilty, what will all us conspiracy theorists find to do with our time?" My suggestion: Beat up on either Lockmart or Airbus Industrie. I will be happy to help out there! Regards, ------------------ Duncan Kunz / duncankunz@cox.net Mesa AZ / 480-891-2525

DEb, you are in serious error doubting the authenticity of that picture, and try to imagine why, if I did know the source of this photograph,I would post it publically..The fact is, Whomever stsed this was a c130 is right, the nomenclature error is on my part, however, that does not change the fact that it is genuine, obtained secretly by an airforce reservist on a NATO mission, not a nasa mission, as has been contended...OF THESE FACTS i AM RELATIVLY CERTAIN....Maybe the reason why the af pilots I talked to told me what they did is because of my long standing friendship with one them, and the fact that i went thru elementary school with him.He was speaking to me off the record in an informal setting as a friend
