video was filmed from another plane as a Boeing 787 flew at 33,000 feet over the east coast of Russia

That'll send the chem-trail people wild.

 

:lol: I thought the exact same thing.

I had to look up Chem trail. That search routed me to Flat Earthers.  Wow. Just... wow. 

 

Makes me want to find a safe space.

Wow is right!

Our chief electrician, now retired, is prior Navy, his MOS was weatherman, and while stationed off the state of Washington, he said the humidity was quite high (something about goldfish swimming around at eye level) -- a Herky Bird fired up, and as those big fans whipped the clear air, it fogged instantly after passing through the blades:  the entire airstrip went from clear to fog in a matter of minutes simply by the air movement from this one big four engine prop job.

I have absolutely no idea if that's the phenomenon shown in the video.

Kind of a Paul Harvey disclaimer:  "For what it's worth!"

If "Chemtrails" were real...or if that was a "chemtrail" dispersion how much chemical would it take to create that big and long of a trail? Kinda like a machine gun in the movies, no?

The exhaust heat from the engines was the biggest 'trigger' here.

When I was a 'ramp-rat' at LAX(WAL)this was common in the mornings, being we were on the edge of the ocean.

Actually, you and Linn are both partially right.

 

Plane propellors and helicopter rotors can create "fog" as the blades pass through extremely humid air.  It's the same phenomenon that creates contrails around fighter jet wing tips when they do high-g maneuvers.  The air forms a very low pressure vortex, and inside that vortex the temperature plunges below the dew point and condenses moisture into a visible fog.

 

As for the "exhaust heat", it's actually the moisture inside the engine exhaust that is a byproduct of combustion.  The engine adds more moisture to the already-humid ambient air until it reaches saturation.  Ta Da!  You get fog.

 

I knew that aero class in college would come in useful one day.:)

Takes all in the correct combo to make this man made fog.

"As for the "exhaust heat", it's actually the moisture inside the engine exhaust that is a byproduct of combustion.  The engine adds more moisture to the already-humid ambient air until it reaches saturation."

This is true for any internal combustion engine. ;)
