    Condensation from engine exhaustThe main products of hydrocarbon fuel combustion are carbon dioxide and water vapor. At high altitudes this water vapour emerges into a cold environment, and the local increase in water vapor can push the water content of the air past saturation point. The vapour then condenses into tiny water droplets and/or deposits into ice. These millions of tiny water droplets and/or ice crystals form the vapour trail or contrails. The vapor's need to condense accounts for the contrail forming some way behind the aircraft's engines. At high altitudes, supercooled water vapor requires a trigger to encourage deposition or condensation. The exhaust particles in the aircraft's exhaust act as this trigger, causing the trapped vapor to rapidly turn to ice crystals. Exhaust vapour trails or contrails usually occur above 8000 meters (26,000 feet), where the temperature is below -40°C (-40°F).[3]Condensation from decreases in pressureMain article: Wingtip vorticesAs a wing generates lift, it causes a vortex to form at each wingtip, and sometimes also at the tip of each wing flap. These wingtip vortices persist in the atmosphere long after the aircraft has passed. The reduction in pressure and temperature across each vortex can cause water to condense and make the cores of the wingtip vortices visible. This effect is more common on humid days. Wingtip vortices can sometimes be seen behind the wing flaps of airliners during takeoff and landing, and during landing of the Space shuttle.The visible cores of wingtip vortices contrast with the other major type of contrails which are caused by the combustion of fuel. Contrails produced from jet engine exhaust are seen at high altitude, directly behind each engine. By contrast, the visible cores of wingtip vortices are usually seen only at low altitude where the aircraft is travelling slowly after takeoff or before landing, and where the ambient humidity is higher. They trail behind the wingtips and wing flaps rather than behind the engines.During high-thrust settings the fan blades at the intake of a turbo-fan engine reach transonic speeds, causing a sudden drop in air pressure. This creates the condensation fog (inside the intake) which is often observed by air travelers during takeoff.

    If you know what you're looking at, it's evidence that there are chemical trails being left by jets that are expanding and joining together to cover the sky. It's not natural. I see it almost every day here in Louisiana. The only proof that they exist is in the sky. If you set aside a day or two (during spraying) to sit outside and watch them with a careful eye, you should be able to rationalize it out on your own. It's hard to deny once you train your eyes and your mind to see what is right in front of your face.

    you sound like a total idiot coming on here and judging someone and making references that half the people on here cant spell. and the"you people " remark made me laugh out loud at you of course

    and how the fuck is this proof? This is why nobody takes you people seriously. You just accept any random shit that is nowhere close to proof as proof. Half of you can't even properly spell let alone uncover any real conspiracies. Did you know that commercial jets fly on specific routes? All of those could either be landing or departing planes from a nearby airport? The last thing I would call this is proof, learn to conduct true research maybe then will someone that actually matters will take you seriously.

    Good footage! Notice at 0:51 there's what appears to be a chemtrail that's very dark in color. I don't thinks it's shade!
