“Dedicated spray equipment”

Dane Wigington's 2021 documentary film “The Dimming” has cemented the “we are being sprayed” narrative for many millions who have watched it. At a mere 2 minutes and 30 seconds into this sci-fi film, Dane claims that high-bypass turbofan jet engines, which are on nearly every commercial and military aircraft, can not create contrails. This is actually false. High-bypass turbofans create more contrails due to their fuel efficiency and lower exhaust temperature.

Contrails form from water vapor created by burning kerosine which rapidly cools and condenses on black carbon (soot) and metal nanoparticles in the exhaust plume.

For a direct test, a formation flight of two different large jet air- craft was arranged, wing by wing, during an ascent and a descent of the aircraft. Contrail formation and ambient conditions were observed simultaneously from a research aircraft. The two contrail
forming aircraft were 1) a Boeing B707-307C built in 1968 and equipped with four jet engines of type PW JT3D-3B with bypass ratio of 1.4 and 2) an Airbus A340-300 built in 1998 with four jet engines of type CFM56-5C4 with bypass ratio of 6.8.

A contrail was observed to form during ascent first behind the A340 at 7:28:40, at flight level 33,300ft. The B707 continued to ascend nearby without a contrail (Fig. 2). About 50 s later, at altitude of about 33,700 ft, a contrail formed also behind the B707 at 7:29:30. The contrails were observed to be forming very suddenly and persisted thereafter. During descent from flight level 35,000ft, the contrails disappeared first behind the B707 and disappeared shortly thereafter behind the A340.
...
As documented in several photographs, an altitude range exists in which the A340 causes contrails while the B707 causes none. Figure 2 shows this fact during ascent and Fig. 3 during descent. The photographs show the contrails best during descent due to the more favorable sun and Falcon positions relative to the two other aircraft. We clearly see the four contrails forming from the four engines of the A340 while the B707 is seen flying without contrails.

Twenty seconds later into “The Dimming”, Dane shows his proof that these are not contrails but are “intentionally sprayed chemicals” for the purpose of geoengineering: Retro-fitted Spray Nozzles. These are not after-market installed spray pipes. In fact, they are pylon drains installed in the Airbus factory, with the purpose of draining fuel or oil leaks to prevent explosions. This is proven by Airbus patents and training manuals for technicians who do maintenance on the Airbus A319, A320, and A321. More Info.

“Increased Cloudiness and Awareness”

You see more contrails now than in the past because:

• There is more air traffic
• Reduced Vertical Separation Minimum (RVSM) means planes tend to fly higher as you can now pack more flights into the higher altitudes, which are more desirable for efficiency, so more planes at contrail altitude.
• Regional carriers are now more likely to use jets rather than turboprops, so fly higher, so more planes at contrail altitude.
• There are more routes now, so more regions see contrails from flyover traffic
• Higher efficiency engines means cooler exhaust, so contrails form in a wider range of temperatures, hence a wider range of altitudes.
• People pay more attention to contrails, because of the "chemtrail" theory, social media, and cameras on every smartphone.
