Can anbody give me a good, clear, clean, and concise answer on how to distinguish between a chemtrail and contrail? In addition, what are the purposes of the chemtrails? Also- does it come from spray nozzles, or is it mixed into the fuel and comes out through the exhaust (which would toast it anyways)?

That's great and all, but how do you explain the flights of B-17's contrails (upwards of 600 aircraft in a single raid sometimes) meshing to form a complete cirriform overcast layer over Europe that would last for days? I thought they didn't start spraying until the 90's?

What do you say to the people that insist that there really are contrails that last for hours and are coverup for the chemtrails?

Also- being the son of a international widebody captain and also having friends that are widebody captains, they bring back alot of great pictures of aircraft that are parralleling them on the North Atlantic tracks (Delta, Northwest, KLM, Lufthansa etc. etc. etc.) making contrails miles and miles and miles long.... Not to mention the pilots will sometimes radio each other their email addresses and send them photos of the other, showing their tremendous countrail going back for hundreds of miles.

Are these innocent civilian aircraft getting chemicals implanted in them and spraying, too? Or are there really long lasting contrails?

i have quoted from science textbooks here many times about the scientific principles of contrails, in brief, they are caused when hot jet exhaust hits cold air.

another factor is moisture in the air. combine these three ingredients and you have instant contrails or man made clouds.

they dont last long because they lose their heat source(jet exhaust) rather quickly. if the air is very wet, they can last for a short whilr, but even then without the constant heat source, they cannot last.

the ww-II trails you speak of were caused by a combination of enggine exhaust caused by the engines beffore smog control. it was early versions of smoggy air.

please see colin powell's u.n. speech as he showed a get releasing chemicals in the air.

chemtrails are unique in that they are not caused by hot air hitting cold air, but by maan made chemicals being released into the atmosphere.

chemtrails don't just linger, they spread out and create what is a lace curtain effect.
this is caused by the chemical reacting to gravity and falling.

contrails don't fall, they either melt or are absorbed into the atmosphere as they are exposed to the sun's radiation.

good luck!

powell held up a picture and showed a video of what he calaimed was an iraqi jet releasing a chemtrail.

this alone should cause the doubters to shut up and go away, but alas, in this new orwellian world, up is down and war is peace!

Which science textbook gave you this boloney?

Piston engines are virtually unchanged in their technology since then. Aircraft now at those altitudes will be usually jet, as opposed to piston at that time.

But actually the average piston engine then is more powerful and complex than the average piston engine now.

There really arent any smog controls on jet engines like on cars. They just make them more and more efficent in terms of burning fuel, but they still put out a lot of gasses.

Smog is a low level photochemical reaction anyways

it is either a lame attempt to look smart or deliberate sabotage of member's ideas. before insulting others or laying heavy criticism ideas for public display, please do some appropriate research.

any textbook on the earth's hydrological system will provide basic facts pertaining to cloud formation, either man made or natural, ie nature's water cycle.

i have posted direct passages of the requirements. heat(sun)and cold(body of water). as the sun evaporates the water it rises and forms clouds. very basic 6th grade stuff.

then as the water laden clouds are blown across the earth and collides with cold air masses, we get rain.

the ww II effects were well documented on history channel's series on effects of war on the environment, especially the early airplane and its habit of smoking badly. it should be available at blockbuster video.

And no, WW2 era piston engines were not smokier. Radial engines smoke when started, but when running were no different. Aircraft piston engines of today are not much different, and often less sophisticated then engines then.

Do you believe that the people in WW2 were mistaken? Were they not running their engines correctly, and only you know this, since only you seem to know this?

The high altitude trails from photos are movies are not just some kind of smoke/smog trails. There were contrails, just like today.

Do you even know what "SMOG" is?

stameyjd- regular cirrus clouds have that wispy, lacy look...because they are ice crystals floating up there. Couldnt this explain the way "chemtrails (long lasting contrails)" look to you?
Also- the contrails made by the B-17's were created by the same reason modern high altitude aircraft create contrails- not because their engines smoked more (ever seen an old 707 or B-52 takeoff?). Contrails are created by the hot water vapor from the engines getting coughed out into the atmosphere and condensing- caused by the same chemical reactions in jet engines as in piston. It's all internal combustion, just in jets it is one smooth action where as pistons have 4 separate "strokes."

For all- to help aid in length estimations- For every 7 seconds, an airliner goes a mile.

From what it looks like- many of you disagree on what chemtrails really look like, as well as their purpose.

Its amazing how ancient the average aircraft piston engine is of today. The horizontally opposed piston engine has probably been around 60 years at least, if not longer.
