Yes, that would be an accurate statement.
But not limited to that alone. There are many types of chemtrails

The video is absolutely not useless and there are literally hundreds more just like it showing planes flying in the same air space, one leaving the smokey looking huge spreading trail and the other leaving either no trail or only the quickly disapating vapor trail.

The video clearly shows one thing and that is that a plane is flying leaving only a vapor trail, while *something else* left a huge smokey looking spreading trail. And too you ignored the most important part of my reply:
If all planes followed whatever it was that the planes leaving the quickly dispating contrails did then we wouldn't be having these white outs and massive 'pollution' clouds blocking out sunlight. It IS possible for planes to fly and not pollute the sky with these nasty looking huge spreading trails, many videos clearly show this, if we can watch planes leaving no trails, fly CLOSE to planes leaving a night and day different polluting trail then people should be demanding that all planes do this. Clearly it seems there is little political will to stops planes blocking out the sun and affecting weather patterns (if only by default) at the least we can say it is INTENTIIONAL because it could easily be stopped and it isn't.

What do you have to say about the use of sulfur-hexa-flouride as an atmospheric tracer?
What about hygroscopic salts in an aqueous solution sprayed into the atmosphere for cloud seeding?
And what about atmospheric barium releases ?
They are put into an aerosol generator and injected into the atmosphere from exterior nozzles on planes.
Then we have the use of chaff for atmospheric studies also.
They are all being used and are all part of what people call chemtrails.

Sulfur hexafluoride (SF6) is an inorganic, colorless, odorless, non-toxic and non-flammable greenhouse gas. SF6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, it is poorly soluble in water but soluble in nonpolar organic solvents. It is generally transported as a liquefied compressed gas. It has a density of 6.12 g/L at sea level conditions, which is considerably higher than the density of air
Tracer compound
Sulfur hexafluoride was the tracer gas used in the first roadway air dispersion model calibration; this research program was sponsored by the U.S. Environmental Protection Agency and conducted in Sunnyvale, California on U.S. Highway 101.[3] Gaseous SF6 is an ongoing commonly used tracer gas for use in short-term experiments of ventilation efficiency in buildings and indoor enclosures, and for determining infiltration rates.
Two major factors recommend its use: Its concentration can be measured with satisfactory accuracy at very low concentrations, and the Earth's atmosphere has a negligible concentration of SF6. Sulfur hexafluoride was used as a harmless test gas in an experiment at St John's Wood tube station in London, United Kingdom on 25 March 2007.[4]
The gas was released throughout the station, and monitored as it drifted around. The purpose of the experiment, which had been announced earlier in March by the Secretary of State for Transport Douglas Alexander, was to investigate how toxic gas might spread throughout London Underground stations and buildings during a terrorist attack. It has been used successfully as a tracer in oceanography to study diapycnal mixing and air-sea gas exchange.
Hygroscopic Cloud Seeding
The term “hygroscopic seeding” has been associated with warm cloud seeding. The objective is to enhance rainfall by promoting the coalescence process using hygroscopic salt nuclei generated by pyrotechnic flares or a fine spray of a highly concentrated salt solution. In addition, Cooper et al. (1997) illustrated that hygroscopic seeding might have a beneficial effect on precipitation development through either of two distinct mechanisms: introduction of embryos on which raindrops form; or broadening of the initial droplet size distribution resulting in acceleration of all stages of the coalescence process.
In 1990, G. Mather reported a case of inadvertent seeding of clouds by hygroscopic particles emitted from a Kraft paper mill in South Africa that resulted in enhanced coalescence and rainfall. This observation led to further hygroscopic cloud seeding experiments in South Africa, (Mather et al, 1997), Thailand (Silverman and Sukarnjanaset, 2000), Mexico (Bruintjes et al., 2001, Fowler et al., 2001) and India (Murty et al., 2000) with highly encouraging results. Additional experiments have been conducted more recently in Texas using powdered salt having particle diameters of 2 to 5 microns.
Hygroscopic Seeding
As noted in Cotton and Pielke (1995) the dominant process for precipitation formation in warm clouds is collision and coalescence. We have seen that this process is very effective in clouds which are warm-based and maritime, or have substantial liquid water contents. The collision and coalescence process among liquid drops is also an important contributor to rain formation in many mixed-phase clouds, and the presence of supercooled drizzle-drops and raindrops enhances the rate of formation of precipitation in supercooled portions of clouds as well.
One method of seeding clouds to enhance precipitation is to introduce hygroscopic particles (salts) which readily take on water by vapor deposition in a supersaturated cloudy environment. The conventional approach is to produce ground salt particles in the size-range of 5-100 , and release these particles into the base of clouds. These particles grow by vapor deposition and readily reach sizes of 25 to 30 in diameter or greater. They are then large enough to serve as ``coalescence'' embryos and initiate or participate in rain formation by collision and coalescence.
Cotton and Pielke (1995) reviewed the various physical and statistical experiments that have been carried out over the years. The results of the statistical experiments were generally inconclusive though some suggested positive effects. Observational and modeling studies provide further support that at least in some clouds, the addition of hygroscopic seeding material can broaden drop-spectra and at least hasten the onset of precipitation formation.
We concluded that `` there appears to be a real opportunity to enhance rainfall through hygroscopic seeding in some clouds. It has not been determined how open the `window of opportunity' actually is. In warm-based, maritime clouds the rate of natural production of rainfall may be so great that there is little opportunity to beat nature at its own game. On the other hand, some cold-based continental clouds may have so many small droplets that seeding-produced big drops cannot collect them owing to very small collection efficiencies. Thus there probably exists a spectrum of clouds between these two extreme types that have enough liquid water to support a warm cloud precipitation process that can be accelerated by hygroscopic seeding.
The problem is ``to identify those clouds, and deliver the right amount of seeding material to them at the right time.'' As optimism for significant precipitation enhancement by static seeding of supercooled clouds has waned, enthusiasm for the potential of hygroscopic seeding has grown. Two ongoing research programs, one in Thailand, the other in South Africa, have contributed to that enthusiasm. The South African experiment was motivated by a report by Mather (1991) which suggested that large liquid raindrops at -10C found in a cumulonimbus were the result of active coalescence processes caused by the effluent from a Kraft paper mill. Earlier, Hobbs et al. (1970) found that the effluent from paper mills can be rich in cloud condensation nuclei (CCN). Moreover, Hindman et al. (1977a,b) found paper pulp mill effluent to have high concentrations of large and ultra-giant hygroscopic particles, which is consistent with the idea that the paper pulp mill effectively ``seeded'' the storm. Another reason for optimism is that Mather et al. (1996b) applied a pyrotechnic method of delivering salt, based on a fog dispersal method developed by Hindman (1978). This reduced a number of technical difficulties associated with preparing, handling, and delivery of very corrosive salt particles.

Still haven't found where this stuff is put into the atmosphere, how about a link?
Post some pics of the planes with chemtrail nozzles? I won't even worry about the last 2 because you seem to not understand what you post because everything you are saying about these being chemtrails is an outright fabrication, again.

The Air Weather Service mission includes the field testing and operational application of weather-modification techniques.
Substantial work has also been conducted in the past 10 years regarding the dispersion and transport of seeding material in both convective and orographic clouds.
The use of tracer material to tag a seeded region has been particularly helpful in this effort. The two tracer materials that are used most often are chaff and SF6. Both materials could be released from either the air or the surface.
The dispersion and transport of the chaff is monitored by radar, while the detection of the SF6 is usually conducted with aircraft equipped to detect it at very low concentrations. (Stith et al. 1990; Klimowski et al. 1998).
