chemtrails

[Typhoon1244]

By the way, about the "Chem Tail" photo:

I've been studying this photo very carefully using PhotoStudio 2000SE. Nevertheless, I'm unable to say conclusively what type of aircraft it is. The shape suggests a Boeing 737-300 or later model...but the fact that the mainwheels are not visible is still causing me to lean toward saying it's a 767-200. It could also be an Airbus A320. The fact is, the photo's too grainy for me to be sure.

I am certain, however, that the underside of the fuselage is white or light-gray, and the visible portions of the upper fuselage are white. This is consistent with the paint scheme adopted by Continental Airlines, as well as some of the "Special" paint schemes used by Southwest Airlines. (Air Canada is also similar.)

In any case, identifying the specific aircraft type is unimportant because aircraft in the photo is not spraying anything from it's horizontal stabilizer. How can I tell? Because if you look carefully at the starboard contrail (the one closer to the bottom of the screen), you can see that it is forming well forward of the tail, just behind the engine itself. It's more obvious if you convert the photo to a negative and/or use some color equalization effects.

So what have you got a picture of? A commercial airliner leaving a pair of contrails in its wake.

Here's one of my favorite pics, shows off those "pencil thin" contrails.

BTW, the colors are from a filter on the camera and the sunset, not representative of true contrail colors

I know that this is coming very late, and his whole lapse rate argument has been debunked, but here goes.
Yesterday flying over east Georgia the surface temp of the airport below me was 18 C, and at 8000' my OAT showed 15 C. How is this possible since temperature always decreases 2 degrees per 1000' no matter what.
Also I lived in San Antonio from 1990 - 1999. There were a couple of summers where the grass did turn brown. But for the most part I was mowing that grass untill the first freeze, which might not come until Janurary (once not at all). Not that this really matters since the surface conditions have no bering on the conditions aloft.

Well they do have a bearing of course, its just not an absolute textbook kind of answer with constantly uniform conditions like chemmies think has to happen.

At least Denver130 has done his share to increase chemtrail awareness here hahaha

Sorry I was being vague, it does have some effect, but there are so many other variables in the equation that surface weather does not predicate what the weather at 12000, or 350 will be.

I'll try not to get to technical, but actually uscpilot, that is just the "Standard/average" lapse rate which we all now know is 2 degrees per 1000 ft. Also their is more then just 1 lapse rate.. such as the dry adibatic lapse rate of 3 degrees per 1000 ft , and the moist adiabatic lapse rate of 1.1 to 2.8 degrees per 1000 ft, however lapse rates will vary based on the latent heat of condensation.

Also keep in mind that your variation in temperature can change based on all sorts of factors such as pressure systems, as pressure increases the air gets hotter, as pressure decreases the air gets cooler.

Uscpilot if you remember that standard temp is 15 c and standard pressure is 29.92 at sea level does not mean that when your at sea level the pressure or temperature will be 15 c or 29.92 on any given day.

sierra pilot,

usc wasnt saying the lapse rates didnt vary. he was using his observations to further debunk denver130s assertions that they are a constant in a sort of a sarcastic way.

denver has an ongoing problem with understanding this concept. go back and read the earlier posts and you'll see just how bad it is.

Sierra,
I would suggest reading more of the thread before responding.

I thought this was supposed to be sarcastic. I read it several times trying to detect it. When I realized he was being serious I about fell over ROTFLMAO.
I could not believe that I was recieving a lecture on lapse rates. Not that I dont need one, this guy probably knows more than me on the subject of technical weather since I havent used it in several years (WSI all the way).
Oh well I am sure he realizes his mistake and is sufficiently embarrased. No back to the topic. I think it was BBQ, Rush Limbaugh, or some gripe with the President.

I had to post again, just because it was about to fall off to the second page.

Did y'all notice that after I suggested that Denver was not who/what he says he is, he vanished?

Interesting...

 

[siucavflight]

Denver is not gone, he is just out on a road trip to photograph chemtrails.
He is starting to wonder why most chemtrails are occuring above these big white cone like objects.

Whats funny is that I actually was jerking their chain once with exactly such a statement on one of their boards. They were really going for it too.

Bumped for the sheer nostalgia of it!
