Then...something as simple as a "Powder Contrail" which was patented in 75.... that means it was around before 75.... that is a single patent .... not counting the 10's of other patents on all this.... and you want to deny they exist?

Your close minded denial of something so obvious is what is fundamentally wrong with your site.

It is true.....planes with no contrail at all....are very hard to spot, and will often go un-noticed.
Yes, if I carefully scan the sky I may find some, so no one is saying it's impossible.
I have often spotted a plane accidentally. If I wasn't looking at that particular part of the sky, at that particular time, I would have never known it was there. This leads me to the conclusion, that often there are planes above me, and I cannot possibly expect myself to see/spot all of them.
Keep in mind, this has nothing to do with "chemtrails", so whether you believe in them or not, is completely irrelevant. It's just a simple principle......planes at around 9.5 km high with no contrail are hard to spot, therefore easy to miss.
There is no agenda in this principle....it's a simple observation.
Visual scanning involves moving the eyes in order to bring successive areas of the visual field onto the small area of sharp vision in the centre of the eye. The process is frequently unsystematic and may leave large areas of the field of view unsearched. However, a thorough, systematic search is not a solution as in most cases it would take an impractical amount of time.
The physical limitations of the human eye are such that even the most careful search does not guarantee that traffic will be sighted. A significant proportion of the view may be masked by the blind spot in the eye, the eyes may focus at an inappropriate distance due to the effect of obstructions as outlined above or due to empty field myopia, in which, in the absence of visual cues, the eyes focus at a resting distance of around half a metre.
A pilot who experiences empty-field myopia is a pilot who is unable to see an aircraft in the distance, despite the unrestricted visibility.
To see something, the lens of the eye must be capable of physically focusing light from the object on the retina. To do this, the eye must be stimulated by an image. If the eye lacks this stimulation, the lens shifts to a resting state some three to five feet away.
When the sky is featureless—as is the case with unrestricted visibility, with hazy conditions, or dark night conditions—you effectively become near-sighted when you look out the windows as your eyes tend to resort to their natural resting state.
To counter empty-field myopia, it is a good practice to focus quite frequently on your own aircraft wing tips. Also, when scanning, focus on distant visible objects or outlines at or near the horizon, stimulating the eyes to establish long-distance focal points.

It's so sad that not even Chemtrailers know that atmospheric humidity, temperature, and pressure affects the visibility of contrails and chemtrails. On a very dry day, you won't see many because the gases will spread out very quickly from lack of condensation.

On the other hand, I've seen planes flying at relatively the same altitude, and one will have a contrail / chemtrail and the other won't. Could someone explain that to me?

You would think someone who was so worried about us, and apparently so versed in aviation, would understand the atmosphere a little better. The temperature and humidity on the ground isn't really a reliable indicator of the temperature and humidity at flight level, keep that in mind.

You can't actually tell the altitude form the ground, they were probably at different altitudes (a few thousand feet). One airplane was flying at an altitude where the conditions were conducive to contrail formation, the other wasn't. The atmosphere isn't homogenous.
The lack of evidence is what proves it isn't happening.
I'll take your word for it, but I don't doubt if you linked to it, the descriptions wouldn't match your interpretation.

Yes. Look at any atmospheric sounding:
weather.unisys.com...
Temperature and pressure both decrease at a fairly steady rate. Temperature drops on average 3.5 degrees every 1000 feet, and pressure drops 4%. So if "a few" means four, then that's a 14 degree drop in temperature, and a 17% drop in pressure.
Humidity can vary much more abruptly, with huge changes in only a few hundred feet.

That's the dumbest statement I have heard today. No it doesn't "prove" it isn't happening...
Ummmmm actually it does.... go find it yourself and read the entire patent ..... it's a very open ended patent that you can do alot of things with...
If you disagree.... then I fear you either won't read the patent or simply can't comprehend it...
An earlier known method in use for contrail generation involves oil smoke trails produced by injecting liquid oil directly into the hot jet exhaust of an aircraft target vehicle. The oil vaporizes and recondenses being the aircraft producing a brilliant white trail. Oil smoke trail production requires a minimum of equipment; and, the material is low in cost and readily available. However, oil smoke requires a heat source to vaporize the liquid oil and not all aircraft target vehicles, notably towed targets, have such a heat source. Also, at altitudes above about 25,000 feet oil smoke visibility degrades rapidly.
goo.gl...
The present invention is for a powder generator requiring no heat source to emit a "contrail" with sufficient visibility to aid in visual acquisition of an aircraft target vehicle and the like. The term "contrail" was adopted for convenience in identifying the visible powder trail of this invention. Aircraft target vehicles are used to simulate aerial threats for missile tests and often fly at altitudes between 5,000 and 20,000 feet at speeds of 300 and 400 knots or more. The present invention is also suitable for use in other aircraft vehicles to generate contrails or reflective screens for any desired purpose.

Well I did not know that. Thank you for clearing that up for me.
although the stated purpose could be used for 'chemtrailing'....but no one has seen these 'powder hoppers' or drive shafts, so I can say with 100% confidence that they aren't.

Your logic baffles me.
Really? No one? No, you can't say that with 100% certainty.
We live on a planet with Billions of people.... I really can't believe you think that.... to each there own
Next you're going to tell me you don't know what a contract is.... /sarcasm
Corporations and Almost our entire government is made up of secrets and contracts and intellectual knowledge that is kept under a lid.
People sign contracts and get paid .....people don't want to lose there livelihood or jobs ...so ya it can be easy to keep it from the public.

point 1. chem trail by definition is a chemical substance sprayed by an airplane.
Originally posted by djcarlosa
point 2 chemical is a very broad term and included many substances.

Therefore any substance used in any kind of aerial spraying can be considered a chem trail by definition.

No, no, no, no, no, no, no. No plane spotters have seen this mechanism, no mechanics have seen this, no pilots have seen this. You're pretty much accusing a lot of people of being incompetent.
