Physical proof, coagulated chemicals from chemspraying over San Francisco, see how nefarious it is? It's designed to stick to one's shoes thereby tracking the chemicals into ones home and infecting everyone there with it's dastardly cargo of mind controlling germs:

If you multiply 2°C per 1,000 feet then you would have a 60°C difference in air temperature from sea level to 30,000 feet (with me so far?). So if the air temperature at ground level is 20°C (68°F) and you subtract the 60°C you get -40°C (20°C - 60°C = -40°C) at 30,000 feet. So we are saying that the air temperature on the ground has to be 20°C (68°F) or colder at sea level for contrails to form at 30,000 feet. I gave an extra 2°F margin for error and I'm just saying 70°F or below at sea level ground air temperature. In swaggers case its even more margin for error since Las Vegas sits at 2,000 feet elevation. So my number is very conservative.


The satellite imagery photo you showed shows chemtrails extending for at least a thousand miles.



Well maybe "never" was a poor choice of words but you know exactly what I meant. See, this is why people don't want to converse with you. You are disingenuous.

and you would be INcorrect

For a contrail to form, suitable conditions must occur immediately behind a jet engine in the expanding engine exhaust plume. A contrail will form if, as exhaust gasescool and mix with surrounding air, the humidity becomes highenough (or, equivalently, the air temperature becomes low enough) for liquid water condensation to occur. The level of humidity reached depends on the amount of water present in the surrounding air, the temperature of the surrounding air, and the amount of water and heat emitted in the exhaust. Atmospheric temperature and humidity at any given locationundergo natural daily and seasonal variations and hence, are not always suitable for the formation of contrails.If sufficient humidity occurs in the exhaust plume, water con-denses on particles to form liquid droplets. As the exhaust aircools due to mixing with the cold local air, the newly formed droplets rapidly freeze and form ice particles that make up a contrail . Thus, the surrounding atmosphere’sconditions determine to a large extent whether or not a contrailwill form after an aircraft’s passage. Because the basic processesare very well understood, contrail formation for a given aircraft flight can be accurately predicted if atmospheric temperature and humidity conditions are known.After the initial formation of ice, a contrail evolves in one of twoways, again depending on the surrounding atmosphere’s humidity. If the humidity is low (below the conditions for ice conden-sation to occur), the contrail will be short-lived. Newly formedice particles will quickly evaporate as exhaust gases are completely mixed into the surrounding atmosphere. The resulting line-shaped contrail will extend only a short distance behind the aircraft.

If the humidity is high (greater than that needed for ice conden-sation 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. Contrails spread because of air turbulence created by the passage of aircraft, differences in wind speed along the flight track, and possibly through effects of solar heating.

All jet fuel is a hydrocarbon mixture containing smallamounts of impurities and additives. The hydrocarbon content of jet fuel produces water vapor as a by-product of combustion. Contrails would not form behind aircraft engines without the water vapor by-product present in exhaust(jet and propellor)


its not just the temp (btw -30'c is -22'f)...and the temp at 30,000 is generally -50'c

Always figure a drop of 2 degrees C per 1K feet in rise as a standard. So if the ground is near sea level, 30K feet would be 60C below ground temp. It varies somewhat, but that's the rule of thumb.



20'c is 68'f (ie room temp)

if the temp is 68'f(20'c) at the ground..it will be generally about -45c at 30,000.......the AVERAGE ground temp is 15'c (59'f)

tex would be wrong as usual

the concord (sst) max cruise hgt was 60,000

the AVERAGE cruising hgt for passenger aircraft is 37,000.....that 37 not 30

the TYPICAL hgts for a 747 is 35,000.....note 35 not 30...and why not higher or lower...FUEL ECONOMY


Prop planes are generally limited to about 20,000 feet...and they still make contrails

This is an intestering thread. Apparantly gravity, mathematics etc. function differently on the homeworlds of some of our posters. But hey, that makes sense given different celestial masses and whatnot.

Someone asked a few posts ago why environmental groups don't complain about the geo-engineering projects ...

U.N. urged to freeze climate geo-engineering projects

(Reuters) - The United Nations should impose a moratorium on "geo-engineering" projects such as artificial volcanoes and vast cloud-seeding schemes to fight climate change, green groups say, fearing they could harm nature and mankind.

Oh, so now chemtrails are not related to taking over peoples minds, changing crops, the new buzzword is geo-engineering huh?

Why is it whenever you have been proved wrong about something all of a sudden chemtrails get associated with some other global conspiracy?

Lets be perfectly clear about what they are urging to occur, shall we?

(from your link)

Since artificial volcanoes are off-topic will not bring that up.

As far as cloud seeding goes there has been attempts as far back as 1903 to seed the clouds...

I find this very interesting because you constantly yammer on about America doing all the chemtrails (ahem, geo-engineering) when in fact the largest country doing this is the PRC.

I find it highly unlikely the PRC allows overflights of secret American chemical aircraft spraying their payloads over the landscape of the PRC.

Unless of course one believes that the National People's Congress is really controlled by the same group that controls the United States Presidency/Senate and Congress...

BTW don9, did you bother to look at the date of that article? Let me refresh your aching eyes:

NAGOYA, Japan | Thu Oct 21, 2010 3:55am EDT

And we all know what a disaster that meeting in Nagoya was....

BTW2 don9, there is no mention of environmental groups in that link you posted:

Quote:
Envoys from nearly 200 countries are gathered in Nagoya, Japan, to agree targets to fight the destruction of forests, rivers and coral reefs that provide resources and services central to livelihoods and economies.
So in chemtrail-speak envoys=environmental groups?
