Its because its proof the people they wanted to label as conspiracy kooks, are actually correct.

Jets do not always make contrails. Contrails are based on the temperature of the air and the amount of moisture in the air.

In your post, the contrail stops. That could be caused by the pilot needing to initiate a descent and closing the throttles to idle.

And piston aircraft can make contrails, too.

I’ve flown formation at the altitudes that contrails form and have seen this coming from my lead. No need to explain why. But it happens without complex conspiracy theories.

They turn jet engine condensation trails on and off at will... LOL.

Videos that haven’t had forensic analysis are meaningless these days. Also, the visibility of contrails comes and goes with different atmospheric conditions. What I want to see is someone gather what is being allegedly “dropped” and analyze it. Until that is done, there is no evidence.

Chem trails are wacky fake conspiracy stuff.
Ever seen pictures of B 17’s in WWII with contrails behind them?

Do people really think there hoses and crews at airports loading this on airliners ?

If there is nothing of any importance in this video, why did Imgur.com delete it?

I have been using them for years and this is only the second or third time something was deleted. The other times I couldn’t figure out what they had deleted, but this time I could.

The deep state couldn’t find 29,000 votes in Wisconsin, but somehow decides to instead prioritize controlling imgur.com? Weird set of priorities if you ask me.

I often see airliners flying overhead my home at 35,000 feet with no contrails and every once in a while a Contrail will disappear just like the one in the gif posted. The grids in my area are formed by planes flying west and east and others flying north and south on regular routes.

Why were people filming this jet? Did they know the trail would go off?

Why are there two videos? One from above and one from below?

The air mass the plane is flying in changes, a normal process when crossing a jet stream or when there is turbulence in the air mass, like mountain waves or frontal passage.

Contrails are confined to narrow bands of altitude, always changing with the moving pressure systems. Weather briefings for fighter pilots always include the contrail altitude so they can be avoided denying detection to adversaries.

The grid patterns are because the planes are following established air routes. The air mass is always on the move, so that when the next airplane comes down that route, the original contrail has translated with the moving air mass. Several airplanes later and you have a set of parallel contrails.

Where there are two crossing airways, you get a grid patterns.

Yeah... there is a massive program of chemicals distributed and loaded onto airliners, and they have spraying equipment aboard. And all the pilots, ground crews and mechanics are keeping quiet about it.
Oh, they put it straight in the fuel and burn it in the engine you say? Cool story... because everyone knows that civil liability is really no big thing in civil aviation. And the oil companies that make jet fuel are not concerned in the slightest about huge quantities of some granular additive in the Jet-A.
And foreign companies like Pratt and Whitney, and Rolls Royce have no worry at all about it going in their engines.

And they are all staying quiet. Silliness....LOL...

That guy that comes by your house every once in awhile that you think is just a meter reader, is actually someone sent to spy on you.

They probably logged into your account and deleted/replaced your image.

Even if you have a smart meter for electric, there’s still the “water guy” that can check the meter from the outside where there’s a small connector.

If you watch him closely, you’ll see him drop a little pellet into your pipes.

I can't say if this is what you are seeing, but you should consider if something like this might be happening. (Any AF pilots or crew chiefs around to comment??)

https://en.wikipedia.org/wiki/Gas_turbine_engine_thrust

"Water, or other coolant,[16] injection into the compressor or combustion chamber and fuel injection into the jetpipe (afterburning/reheat) became standard ways to increase thrust, known as 'wet' thrust to differentiate with the no-augmentation 'dry' thrust.

Coolant injection (pre-compressor cooling) has been used, together with afterburning, to increase thrust at supersonic speeds.[17] The 'Skyburner' McDonnell Douglas F-4 Phantom II set a world speed record using water injection in front of the engine.[18]

At high Mach numbers afterburners supply progressively more of the engine thrust as the thrust from the turbomachine drops off towards zero at which speed the engine pressure ratio (epr) has fallen to 1.0 and all the engine thrust comes from the afterburner. The afterburner also has to make up for the pressure loss across the turbomachine which is a drag item at higher speeds where the epr will be less than 1.0.[19][20]

https://aviation.stackexchange.com/questions/96674/how-much-does-water-injection-improve-thrust-of-a-jet-engine

Snip.... "Note that water injection increases thrust by accelerating the water mass (and also increases engine performance by cooling); similarly, the mass of added fuel in afterburning also accounts for part of the added wet thrust. In this sense, given that afterburning engines get around two thirds more thrust, effectively by quadrupling fuel consumption, when a significant portion of that thrust is from accelerating the fuel mass, not just from combustion, it is understandable that we might start to wonder if we should swap a few hundred gallons of fuel for water.

I think the numbers on SFC (specific fuel consumption) for afterburing engines are worth commenting on here because the inefficiency is insane, whereas water is rather cheap. For afterburning turbofan engines, fuel flow usually quadruples in reheat. The SFC in the F-16's FW100 increases from 0.76 dry to 1.94 wet - dry thrust being 17,800 lbs and 29,160 lbs wet. When calculating with FW100 thrust figures, dry fuel burn at sea level is 225 lb/minute, but in reheat/wet it's 943 lb/min. So by more than quadrupling the fuel burn, the result is just 64% more or 11360 lbs additional thrust. Considering the F-16 has 7000 lbs internal fuel, this is a heavy price to pay for 64% more (sea level) thrust and it certainly makes an additional 30% thrust from water injection sound appealing at first glance.

As far as actually commercially "budgeting" for wet thrust, the Concorde was the only afterburning commercial aircraft, so it would be interesting to know how close they were to adopting water injection. It would appear the weight savings with afterburners was more important than the cost savings of a heavier water injection system.

For the purpose of civil experimental aircraft it would be extremely interesting to see how water injection could be employed and if a similar 30% boost is achievable. Given that the small TJ-150 engine produces 337 lbs max thrust and probably burns 50 GPH at sea level, the prospect of getting an additional 100 lbs thrust for minimal cost or weight, even for a few minutes, would be very appealing.

Edit: I should also add that the Honeywell TPE331 turboprop engine gains an additional 10% power - Augmented 5 min Rating - from water methanol injection.

And:

This reminds me of the supposed Chinese ICBM launched from a sub off the west coast threads from back in the day. Anyone recall that? Half of FR was convinced it was a sub launch and half thought it was a jet contrail the helicopter pilot filmed head on coming up over the horizon.
