This is not about believing, this is about knowing. I know full well what I have, on several ocasions now, seen. The only thing I do not know, cannot really know, is the precise nature of what is being sprayed, beyond the fact that it seeds clouds over massive areas in a relatively short period of time and appears to have adverse effects on life on the ground.
And you're not being truthfull about his links, as many are relevant. Also, you have to understand that if this is indeed covert there will be no official links about this as it's being suppressed and lied about. Possibly by people like you.

Lets have a look, sky is clearer in summer so you see more CON TRAILS
although it may be warm at ground level in the summer at 26-40,000 feet its
really cold!!!! or dont you know that
Are you people seriously saying that every passenger plane is pumping out chemicals I wish I was a psychology student the net would keep me busy for life!!

It's all of those. The sky is a fluid (as all gases and liquids are - they 'flow', hence 'fluid'), and it is not homogeneous - it is made up of pockets of vastly different temperatures, humidities, wind speeds, everything. And old jet engines and new jet engines run at different speeds, at different temperatures, and expel different amounts of exhaust, simply because technology has moved on a lot in 40 years.
And yes, of course there are more 'chemtrails' in the winter, as they are formed by hot exhaust condensing in the colder atmosphere. The colder the atmosphere, the more condensation. Just like you notice your breath when you breathe outside more in the winter - or is that 'chembreath', something else we should all be scared of?
It's not ridiculous - it's called "science".

All the evidence suggests yes - it is just aircraft-induced condensation.
Did you read that PDFI posted? It explains most of the things you seem to not understand. It's no fault of your own - meteorology is not usually taught to most people. What is clear is that the colder the air around an aircraft (as one might expect in Winter) would lead to more contrails. Just as you can see your breath when outside in Winter, you can see contrails behind planes - they are made by the exact same phenomenon - condensation caused when hot humid air meets cold air. The water vapour in the hot air is instantly cooled by the cold air, and becomes visible.

It would require a fueled and ready jet at every airport in the nation, set up in advance with the necessary equipment and a pilot on hand to fly it into a suspected Chemtrail to do the testing.

Aircraft, engines, chaff, and flares can produce a variety of condensation patterns (or contrails), exhaust plumes, vapor trails, or smoke patterns. The exhaust emissions produced by aircraft and space launch vehicles can produce contrails that look very similar to clouds which can last for only a few seconds or as long as several hours. Vapor trails are formed only under certain atmospheric conditions and create a visible atmospheric wake similar to a boat propeller in water and usually dissipate very rapidly. Chaff and flares produce unique smoke patterns that are visibly different than a contrail but have the same color and appearance as a cloud but which also typically dissipates very quickly. Aerial spraying for pest or weed control and fire
suppression are the only Air Force activities which involve aircraft intentionally spraying chemical compounds (insecticides, herbicides, fire retardants, oil dispersants). In the case of an in-flight emergency, jet fuel may be released to lighten the landing weight and minimize the risk of fire if the aircraft should crash.
Aircraft engines emit water vapor, carbon dioxide (CO2), small amounts of nitrogen oxides (NOx), hydrocarbons, carbon monoxide, sulfur gases, and soot and metal particles formed by the high-temperature combustion of jet fuel during flight. Of these emittants, only water vapor is necessary for contrail formation. Sulfur gases are also of potential interest because they lead to the formation of small particles. Particles suitable for water droplet formation are necessary for contrail formation. Initial contrail particles, however, can either be already present in the atmosphere or formed in the exhaust gas. All other engine emissions are considered nonessential to contrail formation.
