The Army used serratia to test whether enemy agents could launch a biological warfare attack on a port city such as San Francisco from a location miles offshore.
For six days in late September 1950, a small military vessel near San Francisco sprayed a huge cloud of serratia particles into the air while the weather favored dispersal.
Army tests showed that the bacterial cloud had exposed hundreds of thousands of people in a broad swath of Bay Area communities including Sausalito, Albany, Berkeley, Oakland, San Leandro, San Francisco, Daly City and Colma, according to reports that later were declassified. Soon after the spraying, 11 people came down with hard-to-treat infections at the old Stanford University Hospital in San Francisco.

Years Ago, The Military Sprayed Germs on U.S. Cities
In Senate subcommittee hearings in 1977, the U.S. Army revealed that weeks before Mr. Nevin sickened and died, the Army had staged a mock biological attack on San Francisco, secretly spraying the city with Serratia and other agents thought to be harmless.
The goal: to see what might happen in a real germ-warfare attack. The experiment, which involved blasting a bacterial fog over the entire 49-square-mile city from a Navy vessel offshore, was recorded with clinical nonchalance: "It was noted that a successful BW [biological warfare] attack on this area can be launched from the sea, and that effective dosages can be produced over relatively large areas," the Army wrote in its 1951 classified report on the experiment.

Get out...thats conspiracy mumbo-jumbo. Couldn't be true right?
Wrong.
Air Traffic Control: By the Numbers
On any given day, more than 87,000 flights are in the skies in the United States. Only one-third are commercial carriers, like American, United or Southwest. On an average day, air traffic controllers handle 28,537 commercial flights (major and regional airlines), 27,178 general aviation flights (private planes), 24,548 air taxi flights (planes for hire), 5,260 military flights and 2,148 air cargo flights (Federal Express, UPS, etc.). At any given moment, roughly 5,000 planes are in the skies above the United States. In one year, controllers handle an average of 64 million takeoffs and landings.
For every one flight you see listed on an airport monitor, two you don't see show up on air traffic controllers' screens. It would take approximately 7,300 airport terminal monitors to show all the flights controllers handle in a single day and approximately 460 monitors to show the number of flights being handled at any one time.

No one is arguing that it's impossible that the government ever put chemicals in the air via airplane...
What's being argued is that there is absolutely no evidence of a large scale chemical spraying program being undertaken by the US government using commerical airliners as the delivery system.
I certainly don't think if dangerous chemicals were being sprayed by the government en-masse they'd do it in a manner that the evidence hangs around at thirty-thousand feet for everyone to see for hours at a time.

The government doesn't need to have an 'official story' on what 'Chemtrails' are, as they are ACTUALLY normal, everyday, persistant contrails Contrails caused by high flying aircraft.
If you want to prove this wrong, then you may as well start by answering the following question.
Why can't Contrails persist and fan out into clouds?
One unique type of cloud is manmade. Contrails occur when exhaust from jet engines condenses. A narrow line of moisture makes up the contrail. Winds eventually dissipate it; in some instances conditions permit the contrail to survive for many minutes (their straight lines do distort). Contrails are believed to affect weather by raising both short and long-term temperatures (one estimate is for about a third of a degree per decade). Here is a MODIS image taken over the southeast U.S. on January 29, 2004 showing a large number of contrails (at times more than 2000 planes are over the North American continent at any one time):

The condensation trails (contrails) that form in the wake of high-flying jets are another interesting example. These cylindrical clouds have variable lifetimes and water concentrations depending on environmental conditions. In some cases the contrails can persist for many minutes. But they do slowly diffuse, much like the smoke plume emitted by an acrobatic aircraft.

Contrails are linear cloud features comprised primarily of ice crystals that are produced from the emission of water vapor and particulates from jet aircraft exhaust into ambient air. Contrails form as a result of the relatively warm aircraft exhausts mixing with the cold ambient air of the middle and upper troposphere. Since most aircraft cruise at altitudes of between 10 and 13 km (typically the 300�100-mb layer), the temperature at contrail level is typically -40�C or colder (Beckwith 1972; Gayet et al. 1996). As a result, most water droplets are thought to freeze spontaneously after contrail formation (Pilie and Jiusto 1958; Boin and Levkov 1994). Once a contrail is produced it typically will last only a short time if the ambient humidity is low, and may never be evident from ground level. Only during a unique range of favorable conditions will contrails persist and spread, both horizontally and vertically, producing a cloudlike sky.

Here is an official NSF report stating the use of nano-technology. Also I will list some other links which show the DARPA connection with all this.

The chemtrail and Morgellons Disease is starting to become more clear in that they are creating a neural network. Morgellons are ACTUAL fibers that could be a reaction to the nano-technology that we are ALL breathing in. We are being wired for the collective hive and once they equip us with the implant chips we are able to be controlled by new technology as in AI computers. Follow this link it will give many DARPA websites that CLEARLY give evidence that this technology is real and WILL be used.

The basic Pitot tube simply consists of a tube pointing directly into the fluid flow. As this tube contains air, a pressure can be measured as the moving air is brought to rest. This pressure is the stagnation pressure of the air, also known as the total pressure, or sometimes (particularly in aviation circles) the pitot pressure.

Now that definitely gets an "A" for creativity but that has to be the most far-fetched paranoid delusional view of contrails that i ahve ever seen. I hope no one really believes that or are getting professional help if so. Good God.

My point in posting though is if this isn't a conspiracy, why don't Russia and Japan have these trails?Just about the rest of the world is getting these and some stories from citizens concerned in other countries never saw these trails until American military exercises were performed.
