WWII Contrails
"We often said that we created weather over Europe. They would persist for many hours, maybe days. "
Jay Reynolds
===========================================
Jay,
Yes, we certainly did. Contrails were so thick that they became clouds. We often said that we created weather over Europe. They would persist for many hours, maybe days. We flew a different route coming back than going in partly to avoid the contrail clouds that we created. There are some pictures of contrails on my web site - none of these are shown to be very heavy but there were time when we were near the end of the bomber stream and the contrails were so dense that it was no dfferent than flying in clouds. A thousand or more planes (4000 internal combustion engines) can make a lot of contrail at 25000 feet or more.
Hope this helps.

So what exactly makes a Chemtrail if this is true then? Their ability to persist? Came across this last night, perhaps you can explain it:
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):
rst.gsfc.nasa.gov...
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.
www.sciam.com...
Contrail formation typically occurs in the upper Troposphere between nine and twelve kilometers is height with temperatures ranging between -35ƒC and -55ƒC (Jensen e. al. 1998, Schrader 1997). Most contrails last on the order of seconds to a few minutes and only a small minority will last for hours as in the contrails photographed (Jensen et. al. 1998). A newly formed contrail will be approximately one kilometer wide and one-half a kilometer tall. As a contrail evolves, it grows greatly in the horizontal plane sometimes extending over 20 kilometers in width (Spinhirne et al. 1998). Examples of this horizontal evolution is shown in the photograph. Contrails can also be 100ís of kilometers long given the right atmospheric conditions and a plane on a steady course.
Long lasting contrails like the ones observed usually occur in parts of the sky that have preexisting patches of cirrus clouds. Since the cirrus clouds are formed of ice crystals like the contrails, cirrus clouds in a region of the sky suggests supersaturation with respect to ice and sufficient heterogeneous nuclei for ice crystals to form (Jenson et al. 1998). The GOES-8 satellite photographs, Figure 3 and Figure 4, taken at approximately at the same time as the contrails were present shows significant cirrus clouds around the Norman area providing a condition necessary for contrail persistence.

Lets just call this what it is, a hoax...
Then lets be done with it.

Yes, what I said about aviation is true. The Chemtrail Hoax started between the two times that I worked an airport job. In the late 80’s to early 90’s there was barely an internet for these topics to be discussed on. Later in 2000 I was not a member of a site such as this, so I did not pay any attention to the topic. Though I had seen it mentioned on one site and dismissed it as some guy that was crazy.
What I did not realize at the time was that there was a whole community of folks that believed in this untruth.
What I can say for certain is that nothing changed in between those times except what I mentioned. Aircraft types, engines, and amount of traffic.
Well if you can recall everything that has been written on this site about the topic, perhaps you know were to find the chart that either Howard or OTS
used to post showing the increase in air traffic. Even if we follow your estimate of 3%, that is 3% over at least 10 years, meaning a 30% increase in traffic.
Another thing that changed is that airlines such as SouthWest sprung up in that time. SouthWest airlines, was a volume carrier, ever at a small airport they add a huge amount to the traffic.
Add to that the fact that they only allow 30 minutes ground time (normally 30 minutes is minimum ground turn time on a 737 that has arrived late, what we would call a burn-turn) on every flight and you can see how this is going to exponentially increase traffic. Other airlines started to follow suit to compete offering more flights that cost less and turning those flights faster, meaning more time in the air for that aircraft during the day.
Essan, has knowledge of meteorology and a limited knowledge of aviation, and I have knowledge of aviation and a limited knowledge to meteorology.
It will be noted that in October of 1997 a change in the reporting system of visibility data was reduced from a former maximum of 40 miles to a limit of 10 miles. It is a reasonable question to ask as to why that change was made, and whether or not it was made in anticipation of certain events to follow that involve large scale aircraft aerosol operations over large scale geographic regions.
It is observed that there are highly significant degradations in the visibility data immediately following this change in the reporting method. Immediately after this change, the dramatic increase in visibility reports of less than 10 miles is quite apparent.
The graphs shown are taken from climatic archive data available for Santa Fe, NM from Jan 1994 to Mar 2001. Three different time periods are shown to aid in demonstrating the magnitude of change which has occurred in visibility. The first graph shows all data available inclusive from Jan 1994 to Mar 2001. The second graph shows the transition zone during which the visibility standards were altered. This graph showns a period from Jan 1996 to Dec 1998; the change in reporting standard was made in Oct 1997. The third graph shows recent data, where visibility below 10 miles is now a regular occurrence. This graph shows the period from Jan 1999 to Mar 2001.

The proposed revisions address two categories of particulate matter: fine particles (PM2.5), which are 2.5 micrometers in diameter and smaller; and inhalable coarse particles (PM10-2.5), which are smaller than 10 micrometers in diameter but larger than PM2.5. EPA has had national air quality standards for fine particles since 1997 and for coarse particles 10 micrometers and smaller (PM10) since 1987
EPA last revised the particulate matter standards in 1997. Under terms of a consent decree, EPA agreed to propose whether to revise the particulate matter standards by December 20, 2005; and committed to finalizing any revisions to the standards by September 27, 2006.
Proposal to Revise the National Ambient Air Quality
Your comparing apples and oranges. So posting questions to me on the subject of anything about the weather would get you an educated guess, but not a fact, you would have to take up that kind of thing with someone like Essan.
Airlines can literally spring up overnight, I have seen it happen: Branif, JetBlue, SouthWest, AmericanWest, Spirit, etc… Branif is a classic example, I have personally seen them file bankruptcy and come back again out of the clear blue multiple times.
Then you get airlines that fail and their newer more efficient aircraft are bought off by other airlines to replace an older aircraft. So the short answer is yes, compared to other large companies, airlines can phase out their older aircraft at a surprisingly rapid rate.
Probably the best-known of the aerial geoengineering proposals was that put forward in 1997 by Edward Teller and entitled ‘Global Warming and the Ice Ages: Prospects for Physics-Based Modulation of Global Change’ subsequently popularised in the Wall Street Journal in an article entitled ‘The Planet Needs a Sunscreen’.
Teller proposed deliberate, large-scale introduction of reflective particles into the upper atmosphere, a task he claimed could be achieved for less than $1 billion a year, between 0.1 and 1.0 percent of the $100 billion he estimated it would cost to bring fossil fuel usage in the United States back down to 1990 levels, as required by the Treaty of Kyoto.
Characteristic of the politics of Teller is the fact that he both ridiculed the idea of global warming and at the same time put forward what he represented as a solution to global warming. ‘For some reason,’ Teller observed sarcastically, ‘This option isn't as fashionable as all-out war on fossil fuels and the people who use them.’

Several schemes depend on the effect of additional dust (or possibly soot) in the stratosphere or very low stratosphere screening out sunlight. Such dust might be delivered to the stratosphere by various means, including being fired with large rifles or rockets or being lifted by hydrogen or hot-air balloons. These possibilities appear feasible, economical, and capable of mitigating the effect of as much CO2 equivalent per year as we care to pay for. (Lifting dust, or soot, to the tropopause or the low stratosphere with aircraft may be limited, at low cost, to the mitigation of 8 to 80 Gt CO2 equivalent per year.) Such systems could probably be put into full effect within a year or two of a decision to do so, and mitigation effects would begin immediately. Because dust falls out naturally, if the delivery of dust were stopped, mitigation effects would cease within about 6 months for dust (or soot) delivered to the tropopause and within a couple of years for dust delivered to the midstratosphere.

Add to this fact that when an airlines starts to fail the first thing that they do is file with the government under re-organization (I think it called chapter 11), at which time the government hands them a huge sum of money to try and upgrade aircraft, retool their image, and make themselves more profitable.

Jet fuel has a specific weight per gallon (with slight variances for temperature and barometric pressure, which change its density/volume) of 6.84. When a jet is fueled it is done by weight (the aircraft gauges are in weight) and totaled to match the gallons on the Hobbs Meter of the pump. The two numbers have to sync up. Both the weight and gallons are presented to the pilot on a service ticket by the fueler so he can check that on his weight and balance prior to departure.
This is all tracked very precisely because it not only effects the weight and balance of the aircraft, but also because it has to be billed by the tank farm to the appropriate airline by flight number.
Well considering that you can go to your local airport and buy a couple of gallons of the exact fuel that is used on the aircraft, what would be the point?
Try it yourself, either go to a small local airport that receives their fuel from the same source, or try the tank farm at a major airport. The only problem your might find with a major airport is that they are gong to want to sell it in a greater volume as its not really worth their time over a few bucks. Truth be told though the gas at your local puddle hopper airport is going to be from the same source as your local major airport. Most smaller airports are shipped fuel from the major airport, which receives that fuel from a port and stores it in a tank farm.
So go track down a gallon or so, and have it tested. If you want to save the time, money, and effort, though:

A chemtrail is a single contrail that lasts for longer than contrails regularly should under normal atmoshperic conditions as clearly suggested in these two extracts.
My question as always remains why people started observing this in American skies right after Teller proposed that spraying chemicals ( thus aiding in persistence) into the atmosphere could negate any effects human industrial activity might have in terms of warming the planet?
Do you not find that odd and why did he bother mentioning additional substances ( to be put in the fuel) if regular contrails were already persistent on any regular basis?
So i am asking you why did he propose this in 1997 which corresponds with the start of people observing strange happenings in American skies?
Why did they change the mean visibility expectations in the same year? What were they expecting to take place?
Why have you not addressed the claims made in the following two sources i have repeatedly provided you with?
Why do these authors suggest that the introduction of additional water vapour by aircraft will not affect the persistence of the contrail?
Why do this supposed scientist then suggest that the water content matters?
Can you resolve this blatant and open contradiction? How often do we find himidty factors of 150% at commercial air traggic altitudes so that the air may become supersatured with ice in the first place?
... you all will just have to be patient and consider coming up with more than just reasurances that 'everything is ok' as i am long long past being able to believe such vapid nonsense.

Ill have to get to the rest of your questions and comments later on, I just got through making a long post and don’t have the energy to make another. Let me tell you something that I observed the other day though.
Here in Tampa it was extremely cold for Florida. I looked up and noticed that the sky was covered in persistent contrails leading into the flight pattern for Tampa International Airport. These were from commercial flights, and they persisted throughout the entire day and slowly spread out to form cloud cover.
The reason that the trails were so severe at this time was easily to discern though. It was like 60 degrees Fahrenheit on the ground here, making it much colder at higher altitudes and thus the formation of ice particles from the water vapor in the exhaust of the normal commercial traffic that flows through the area on its way to the airport.
Guess what else…
The trails all intersected in big X’s just to the east of I-275. This is due to ATC funneling the aircraft into an approach pattern to the airport to make a southern approach into a northern landing.
Thus here we have all the earmarks of what folks consider Chemtrails, and the only reason that they existed is due to the temperature.

Sorry Stellar, I'm only online when at work, so not always able to devote as much time to this as I'd like
You reference these sites which refer to contrails persisting for several minutes. And it's true that most of the time contrails - if they even form at all - do last for at most just a few minutes.
However, I've also linked to meteorological sites which clearly explain that under certain conditions they can persist much, much longer and even spread out to form large sheets of cirrus (which I've seen happen myself). The atmospheric science behind this is well known and well understood - and has been for decades.
Now, if something were being sprayed by commercial air traffic, wouldn't it also only appear to linger in the sky as clouds when the atmospheric conditions were ripe for persistent contrails to exist and spread into cirrus clouds? Thereby making it impossible to differentiate between contrails and chemtrails?
If the purpose of chemtrails was to spray the countryside/populace with something, it would make far more sense to only carry out such operations when persistent contrails are unlikely to form. Therefore ensuring no-one sees you.
If, as some claim, chemtrails are intended to form clouds for some form of climate experiment then nothing would actually need to be sprayed - just an increase in air traffic at the altitude at which atmosphere conditions are ripe for contrails to linger anyway would do the job.

I think that it may have more to do with the coincidental rise of the internet around the same time.
To which I would add that if Teller's scheme were implemented, it's clearly having no effect whatsoever.
"Q: Let me ask you specifically about last week's scare here in Washington, and what we might have learned from how prepared we are to deal with that (inaudible), at B'nai Brith.
A: Well, it points out the nature of the threat. It turned out to be a false threat under the circumstances. But as we've learned in the intelligence community, we had something called -- and we have James Woolsey here to perhaps even address this question about phantom moles. The mere fear that there is a mole within an agency can set off a chain reaction and a hunt for that particular mole which can paralyze the agency for weeks and months and years even, in a search. The same thing is true about just the false scare of a threat of using some kind of a chemical weapon or a biological one. There are some reports, for example, that some countries have been trying to construct something like an Ebola Virus, and that would be a very dangerous phenomenon, to say the least. Alvin Toeffler has written about this in terms of some scientists in their laboratories trying to devise certain types of pathogens that would be ethnic specific so that they could just eliminate certain ethnic groups and races; and others are designing some sort of engineering, some sort of insects that can destroy specific crops. Others are engaging even in an eco- type of terrorism whereby they can alter the climate, set off earthquakes, volcanoes remotely through the use of electromagnetic waves."
So there are plenty of ingenious minds out there that are at work finding ways in which they can wreak terror upon other nations. It's real, and that's the reason why we have to intensify our efforts, and that's why this is so important.

I would assume that was because persistent contrails do not form on that regular a basis over the planet as a whole - they are more prevalent in some areas (mid continental regions) where high pressure leads to more frequent occurrences of the necessary atmospheric conditions.
However, is there any reason to believe that Teller's plan was implemented?
Other serious proposals he made - like using a hydrogen bomb to create a deep water harbour in Alaska were not implemented, even though the scheme was accorded a project name (Project Chariot)
It appears to me that it was more of a slightly tongue-in-cheek suggetsion - and in any case, I would hope the US Govt would not start such a scheme based solely on the suggestion of an elderly nuclear physicist - no disrepect to Teller, but there are hundreds better qualified and experienced atmospheric scientists out there.
I wouldn't have thought such changes were introduced purely on the basis of a scheme proposed at the same time - surely the scheme (if taken seriously) would be investigated further first?
Livingston, 77, moved to Midland with his parents during the Depression. He earned his master's degree in cloud physics from the Naval Weapons Center and Navy Post Graduate School in California, a degree he would use in the battlefields. He seeded clouds and dramatically increased rainfall in his theater of war, creating impassably muddy roads, slowing down the Vietnamese and Korean troops, and saving lives and entire towns from occupation.
He is proudest of his award from the secretary of Navy, which says, "Lt. Livingston directly participated in project flights in a combat zone, in program planning, scientific data collection and evaluation ... his unwavering devotion to duty were major factors in the outstanding success of the project and were instrumental in the development of a unique, major combat capability for the United States."
Before receiving the citation, Livingston was invited to the White House where he briefed President Lyndon B. Johnson on the effectiveness of weather control activities and the resulting slowing of traffic by the military support trucks bringing supplies to Southeast Asian troops.
Livingston works with scientists and pilots at Weather Modification Inc., in Fargo, N.D. His theories also have been verified by staffers there. He has logged 15,000 hours of hurricane reconnaissance experience and all of his penetrations into the eyes of hurricanes were of the low-level variety --
"In the 1960s, a national priority of our government was hurricane control," Livingston said. "Silver iodide is used as a nuclei that causes raindrops to form. The original hypothesis is that if you get enough rain or cool air into a hurricane you can diminish its velocity and strength. When I left the military in the 1960s, we had the ability to do that, and reduce wind velocity in hurricanes by 25 percent and damage caused by a hurricane by 63 percent."
Livingston said his research of hurricane control was confirmed by the Stanford Research Institute. The program of controlling hurricanes, though, was mysteriously dropped by the federal government because of, as he termed it, "politics and professional jealousy." Livingston said powerful Washington lobbies control areas preventing the reinstatement of the hurricane-reduction program, and when asked why it has not yet been resinstated, Livingston cites what he calls an "industry of destruction."

And it would take time to set up the manufacturing and distribution of the substances to be sprayed.
The sites you mention are correct: in some cases contrails can persist for many minutes.
But that does not mean that they cannot less commonly persist even longer, nor
that all meteorological references stating that they can form into sheets of cirrus are wrong.
After all, the sites do not specify that often contrail don't form at all
I think you're confusing the water content of the fuel with the pre-existing humidity level of the air around the aircraft - the one doesn't matter with regards contrail persistence, the other does.
Due to the physical structure of ice, the humidity level actually has to be higher, about 150 percent humidity level, than it would be for the air to be supersaturated with water.
"The exhaust (jet engine) injects a lot of water into the air," Minnus said.
"The water droplets immediately freeze and you wind up with a contrail."
Minnus said once the contrail is formed in supersaturated air, larger ice particles become nuclei and begin to grow, collecting other ice particles from the surrounding air.
As the particles get heavier, they begin to fall out of the contrail, spreading it vertically, wind shear spreads the contrail horizontally as it continues to collect ice from the atmosphere.
www.journalnet.com...
* Long-lived contrails cannot be explained by the amount of water emitted by the aircraft. Although we have not performed a simulation in an atmosphere that is subsaturated with respect to ice, it is quite obvious (in comparing results from runs 3 and 8) that persistent contrails can only form in an atmosphere that is supersaturated with respect to ice.
ams.allenpress.com...(1998)055%3C0796:LESOC%3E2.0.CO%3B2
I'm not sure though how common supersaturated air like this is.
do appreciate that. Even if my responses aren't always that useful ...

It´s no secret that contrails do influence the weather and can be the seed for clouds.
But that´s just normal. Noone denies that and there is no conspiracy

"The system had 1 large and 2 smaller tanks. It was hard to tell in the cramped compartment but it looked like the large tank could hold 50 gallons. The tanks were connected to a fill and drain valve that passed through the fuselage just behind the drain valve for the waste system. When I had a chance to look for this connection under the plane I found it cunningly hidden behind a panel under the panel used to access the waste drain."
