NASA and Boeing try to chase the contrail clouds away NASA is studying contrails to determine if more environmentally friendly aircraft fuels might reduce their formation. Contrails are lines of clouds left by high-flying aircraft formed when water vapor in engine exhaust condenses and freezes. The clouds themselves are made up of ice particles and some scientists worry that a …
Since they didn't communicate with Bill Gates in advance it turns out the chemtrails deactivate the 5G chips in our bloodstream. If there are no more chemtrails then those 5G chips go active and ... well I'm not sure what happens but I'm sure it isn't good and will make Bill Gates even richer!
Seeing as "6" is the number of the beast and the word for "6" has three letters in it, this makes the expansion of it 666G. We all know that that means don't we? It's simple, sheeples, G is the 7th letter of the alphabet meaning that the real plan will be executed with the turn on of global/flerfal 7G technology. 6G is our last chance. All poles having HD 6G wires attached to them must be immediately burnt down. Especially if these poles are attached to each other in any way, forming a network of control and manipulation.
They may be able to reduce the particulate emissions from powered aircraft, but gliders (sailplanes in the USA) can also produce vapour trails in flight. Just google "Glider creating vapour trail' for some photographic evidence.
Still, reducing high altitude pollution has got to be a good thing.
Certainly the area of lower pressure created over the airfoil could cause moisture vapor to condense. That's a plausible mechanism.
But with jet aircraft you also have additional vapor as a combustion product, and other exhaust components as nucleation sites. IANAC, but it seems to me that there's potential (in theory) for reducing contrails formed by jets, even if you can't eliminate them entirely.
Sorry, but no.
Gliders can create something that looks like a vapour trail when dumping waterballast, but this is very temporary, and the mechanism is quite different.
If the water content in the atmosphere is very high, then low pressure areas over a wing surface or at the tips of wings and propellers can trigger to vapour (see fighter jets flying transonic inside a lens shaped cloud), but this will dissapate again almost immediately once ambient pressure is restored.
Gliders have such low wing loadings (currently up to approximately max. 60 kg / m^2), that you must be very lucky to see under-pressure triggered vapour trails example: https://youtu.be/cFgwmap8SW0?si=vzkGDeP1w5LQbuco .
Vapour trails from airliners are completely different beasts. Jet engines burn hydrocarbons. The carbon part combines with atmospheric oxygen to create CO2. The Hydrogen part combines with atmospheric oxygen to create water steam. This steam is then rolled up into the trailing wingtip vortices and, if the atmospheric conditions are right, condensates into a linear cloud that can last for quite some time.
Soot particles from un-clean combustion may also help in the process. IIRC, running the combustion hotter may reduce soot, but increase NOX formation.
Replacing hydrocarbons with hydrogen will remove CO2 and soot, but the other issues remain.
I grew up in the middle of Western Kansas--the very definition of fly-over country. Contrails behind jets can disappear in several jet-lengths, in several seconds, in several minutes, in a few hours, or... and this is NOT particularly rare, grow until the merge with others and keep growing.
Once the turbulence dies down, they are EXACTLY the same as any other cloud, and if the local atmosphere is supersaturated, they will grow to the limits of the supersaturation.

So water, in the sky = pollution.
Oh, drat! I just started raining. Now the pollution is everywhere!
