Speed.

Contrails are formed by water vapor being super-cooled as it passes through a jet engine. The frozen vapor is quickly melted by the sun. This phenomena only occurs above 35000 feet, and the humidity and barometric pressure has to be just right. The lines seen crisscrossing our skies today are not contrails. They are man-made clouds, most likely used for weather modification...what many people call "chemtrails".

Super-cooled jet exhaust? What the hell are you talking about? Jet exhaust is hot enough to burn the flesh off your bones.

Does this look super-cooled: https://www.youtube.com/watch?v=vXXECdFJZSQ

The videos you provide are showing jet engine tests at ground level. What I am talking about is at 35,000 feet. After the water vapor passes through the jet engine at high speed, it is returned to below freezing temperature in the atmosphere. The water vapor briefly turns to a crystalline fog that then quickly melt. It is how contrails are formed.

old_grumpy_fucker

No shit. Now explain why you were calling jet exhaust super cooled.

Contrails appear and disappear according to the temperature of the air and how much humidity exists at that particular spot. Air at that altitude is pretty much like ocean currents. Temps and humidity around the aircraft can change quickly. They aren't controlled by some switch in the cockpit.

When the vapor comes out at speeds around 500 mph it is thrust back into very cold air, approx -30 to -40 degrees F. 500 mph into -30 F. It is cooled very very very fast. As fsr as pilots not being able to control contrails with a switch, I agree. Look at the video that is posted of a pilot painting a dick in the sky. In order for him to do that, he was turning a sprayer on and off. The dick is not a contrail.

old_grumpy_fucker

Oh, right. And the earth is flat.

Do you ever wonder why people who have worked around aircraft usually think that you're a lunatic? Seriously.

Go look up the definition of super-cooled. If the plane had been a few thousand feet higher or lower there probably would not have been anything to see. It all depends ond the temperature of the air layer.

I saw my first contrail in 1965 when I was four. It was a short trail that disappeared almost as quickly as it formed. I asked my mom if the plane was on fire. She laughed and told me it was just a jet trail. I was intrigued and by five or six years old, I was reading from encyclopedias and library books on contrails and clouds and weather. When I was in my teens, when I was with my friends and saw the relatively rare contrail, I would point it out and humorously yell, "That plane's on fire, they're all gonna die!" I've played and worked outside almost all of my life, and I've always watched the sky. Planes never ever left trails that stretched across the sky. Early one morning in May of 2007, I looked up and saw two planes leaving long dripping trails across the sky, then they both did a 180 and continued spraying. In over 40 years of watching the sky above the bayous of sw Arkansas, I had never seen that. It continued over that summer, checkerboards being painted over the entire sky. So I know for a fact there is a difference between contails and chemtrails, and I don't give a fuck what some anonymous braindead shithead on the internet says.

old_grumpy_fucker

Yeah, sure. Your 4 year-old mind is a reliable source to consult for answers on meteorology and aeronautical principles.

Shit like this is how early people were conned into believing that gods existed.

But by all means, continue tilting at windmills. That way your brand of lunatic is safely occupied away from normal people.

grandmacaesar

Fuck you, Mick West.

old_grumpy_fucker

Reeeeeeeeee much?

grandmacaesar

No. Not at all.

Inara__Serra

Partially incorrect. Old radial engine aircraft also left contrails.

They are formed by aircraft at altitude. Period. The moisture content in the air at that altitude and whether that air is warm or cold determines whether or not there are contrails.

Chemtrails are figments of the imagination.

grandmacaesar

These are military aircraft, and in the two videos you provided they are obviously able to turn the trails off and on. You say "chemtrails are figments of the imagination". You are a liar, either lying to yourself because you can't handle the truth, or lying to aid and abet a crime against humanity.

Inara__Serra

Of course they were military aircraft. THERE WERE NO CIVILIAN AIRCRAFT CAPABLE OF FLYING AT THAT ALTITUDE.

Contrails are a function of moisture in the engine exhaust, air temperature, and altitude. Air temp and humidity varies at higher altitudes.

Believe what you want. You obviously have your mind made up, and I'm not going to waste my time explaining again.

WhyNoDonuts

Afterburners maybe? What kind of planes sho the zappers use?

FortressOmega

Ah the ol' penis maneuver. Many of pilots have succumbed to the this hairy tactic. The climax, multiple side winders shooting at the target on the final thrust. Man it is a spectical.
