Yes, they are either lying or just misinformed and mistaken.
Look at the size of the whole engine on an older turbojet engine like a Boeing 707 and then look at the size of the engine on a newer plane like a Boeing 777.
The newer plane has a MUCH LARGER FAN.
So although a large percentage of the air is not passing through the combustion chamber, the same amount of air IS going in as in the older design, because the intake to the combustion chamber is about the same.
Plus, what makes the water is burning the hydrocarbon. As the newer engine is more efficient a slightly smaller amount of hydrocarbon will be burnt to create the Carbon Dioxode and the Water which comes out the back of the engine. The extra air that doesn't pass through the combustion chamber is neither her nor there.
It's also impossible to prove a negative. Plus this website is meant to be about debunking individual claims, rather than discussing wider conspiracy theories.
But if every piece of "evidence" that comes along is bunk, then there is no reason to believe such a thing is happening.
People are talking about Geo-engineering. If people like Bill Gates, or the US Military, wanted to secretly do some of this stuff, why the hell would they openly talk about it,and say that BEFORE this stuff is done, we need to OPENLY discuss this to make sure we think it is the right thing to TRY OUT rather than just do it and say nothing?
So those lines in the sky sure are water vapour. I'll tell you why as well, a lot of people here, including me, have done the maths. Try it yourself. Pick a plane that makes a trail, (decent enough shot so you can read the registration number), find out exactly what plane it has, and all its specifications. Work out how big you think the trail is and crunch some numbers.
In this thread:
https://www.metabunk.org/threads/chemtrail-additives-in-jet-fuel-a-mathematical-analysis.4426/ I worked out that the plane G-VBIG ( a boeing 747 with GE CF6-80C2B1F engines), even if it was a magic plane that did not require fuel to fly, if the entire weight of fuel was used to make a "chemtrail" then its concentration just as it left the back of the plane and before it spread out was only 0.16g/m3.
If you look at a plane's specs, you will also see that the fuel makes up a lot of the weight of the plane, so once you subtract the weight of fuel AND the weight of the empty plane from the Maximum takeoff weight, the amount of PAYLOAD (i.e people or chemtrail material) is less than the weight of fuel, so if the chemtrail stuff is NOT in the fuel, there is even less of it in the plane.
Using these specs for a 747-400 Freighter:
http://www.boeing.com/boeing/commercial/747family/pf/pf_400f_prod.page?
and this conversion chart:
http://www.streamline-ops.com/en/info/fuel_weight_conversion_tables/
gives you a fuel weight of 173,472 kg but a payload of only 112,630kg.
So basically these 200 mile long trails seem to have far too much material in them to fit in the plane.
Is it not a possibility then, that MOST OF THE MATERIAL is already in the air (i.e water at nearly supersaturated levels)
Being a paid shill is a HELL OF A LOT less lucrative than being a major chemtrail promoter, selling your vids, T shirts, chembusters, posters, and having big donation buttons all over your page.
And once you go down the route of accusing people of being paid shills with no evidence except that they don't agree with you, just shows you have no real argument and cannot refute any of the evidence or debunking that they show you.
