I do suspect more than a healthy dubious dose of distrust. Because I DO think every elongated trail is a result of aerosol spraying.
Do you really believe that?.......do you really think that if the temps and humidity at a certain altitude are conducive to the formation of persistent cirrus clouds, that the ice crystals formed from the water content of the jet exhaust, will not allow for the formation of a persistent contrail?
You think if it hangs around it must contain chemicals?......really?

Of course not. I see contrails disipate after a while. Not so with other thicker trails that spread out until it forms a wispy cirrus-like cloud. This is what the bulk of my sky looks like by 4PM thanks to these planes.
Okay. Let's say once again assume these are regular persistent contrails. I say we pass legislation and get a decent sized muffler on said-planes so not to make my clear sky, cloudy. I moved to Florida for the sunshine. Now we get chem-shine.edit on 24-2-2012 by Human_Alien because: (no reason given)

And I just love these planes that appear to be launched from the middle of the Atlantic that shoot straight up, leaving a thick persistent 'con' trail as far as the eye can see, which lasts for hours and covers the entire county if not, east coast of Florida.
Case solved. Thank you!
Q) How long do contrails last?
A) Anywhere from less than a second, up to several hours. If depends on the atmospheric conditions at the altitude the plane is flying. It’s unrelated to the weather on the ground.
This is an oft-asked question. The answer is reasonably straightforward, but misunderstanding is common. To understand why a contrail can last as little as a fraction of a second, or as long as several hours, you need to understand what a contrail is, and how it forms.
Here’s another question, which has the same answer:
Q) How long does a snowflake last?
Why is this basically the same question? Because contrails are generally made of ice crystals. Jet exhaust contains a lot of water vapor (the chemical reaction actually produces more water than there was originally jet fuel), and when this gets shot out of the back of the engine at 2000MPH, it hits the frigid air (typically colder than -40 degrees), and the water vapor condenses and freezes, very quickly, into tiny ice crystals, just like snowflakes.
So why do these ice crystals sometimes stay around for a long time, and sometimes vanish in seconds? The temperature is well below freezing, so they can’t melt, can they? This is puzzling, because it involves something that most people know nothing about: “sublimation“.
Sublimation is when a substance (in this case, water), goes directly from being solid to being vapor (a gas), without actually melting into a liquid. It’s like evaporation, except instead of a liquid evaporating, it’s a solid (ice). If the air is dry (i.e. there is little water vapor in it), then the ice crystals will quickly sublimate into vapor, and the trail will vanish quickly.
However, if the air already has a lot of water vapor in it, then the ice will sublimate slower, and the trail will last longer.
If the air has so much water vapor in it already that it can’t hold any more (i.e. it’s “supersaturated”), then the ice crystals can’t sublimate, and so the contrail will stay around for a long time. The ice crystals might even attract water from the air, if there is enough, and the contrail will get thicker. Winds might make the contrail spread out to even cover the whole sky.
The above is a simplification, as other factors like temperature, pressure, and sunlight have an effect. But it explains the basic reasons why some trails last only a few seconds, and some can last for hours, and spread out to cover the sky.
Finally, there is one more way of asking the question:

You know, once a upon a time, not too long ago in fact, Galileo could NOT prove the world was round. But in time, his claimed proved correct.
My mission in this incarnation (unless I missed the memo) is not to prove this phenomena exists. It's out of my expertise. I leave it to others with more clout and more resources to fight this for me.
And believe me, I have more 'cases' to crack (like proof of extraterrestrial life and their abductions) so this is chump-change to me. Well, not really. But it's not my forte therefore I can't go toe-to-toe with naysayers. Too much wasted energy for me.
I just know the government keeps secrets and they have no problem what so ever to use and dispose of us at will.
If that notion doesn't bode well with your beliefs then, you're a denser and a much better person than I because I WISH I could ignore all that I know.
Hope this helps to give you a true depiction of me.

You don't buy the fact of air pockets? a proveable, known thing.. but you do buy into the insanity that is chemtrails, the thing that has zero evidence whatsoever =) .. let me guess, you also believe in the tooth fairy?
