engineered nanoparticles could exploit photophoretic forces, enabling more control over particle distribution and lifetime than is possible with sulfates, perhaps allowing climate engineering to be accomplished with fewer side effects. The use of electrostatic or magnetic materials enables a class of photophoretic forces not found in nature. Photophoretic levitation could loft particles above the stratosphere, reducing their capacity to interfere with ozone chemistry; and, by increasing particle lifetimes, it would reduce the need for continual replenishment of the aerosol.www.pnas.org...

See? This thread, your photos, prove nothing about "chemtrails". Since really...."chemtrails" simply do not exist in the first place; this is known. However, the images are indicative of what is observed frequently, and well understood by many, of contrails.

So give that the observed phenomena match something that is known, and his attempts to show they can't possibly be that are incorrect, the answer to the thread title question is obvious:

Nope.

Prove it.

You are the one claiming that aircraft are conducting geoengineering - I am pointing out that you have no actual evidence of that, and that what you saw matches known chemtrail behaviour.

so how about you prove it, since you are the one claiming something is happening?

I gave all the pertinent data, Those contrails could not have formed by the planes on the radar, besides there were a great many more than were listed on the radar, the pics prove that also.

Rubbish - the pics show a couple of handfuls of planes, which is entirely consistent with the computer plot.

All I hear from your camp is denial.

Again rubbish - you have had a great deal more analysis offered than you yourself gave - all you have done is said "planes in the sky = geoengineering?" - without even bothering to count how many!!

A portion of those reading will fall for the trap, those that want to be secure in their beliefs... the mainstream media does the same thing night after night. Those that want to look at the data will see a different picture.

Those that actually look at data see you have none for your case.

Contrails are unaduIterated and typically disappear within 2 minutes while chemtrails can linger for hours.

If the humidity is high (greater than that needed for ice condensation to occur), 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.

But one thing I am a little concerned about is where you state "The ones that were not making the spreading contrails show on the radar, the ones that were making the spreading contrails are not shown." How can you be certain that none of the planes on the flightaware screen grab are producing contrails?
