This news report is from 1980.
It’s based on this research paper:
EFFECT OF CONTRAIL CIRRUS ON SURFACE WEATHER CONDITIONS IN THE MIDWEST
(Searchable/Copyable OCR version here)
It’s interesting because it shows that back in 1980 people were noticing contrails persisting and spreading to cover the whole sky. At that point people had even noticed it contributed to increased cloudiness.
This is a useful video to show to anyone who thinks that this is a recent phenomenon. For more details, the research paper also makes it very clear that contrails in 1980 were just the same as contrails in the present day.

Clouded Judgment: Do Jet Contrails Increase Cloud Cover?
JOHN CHANCELLOR, anchor:
On clear days, you can often see long white lines being traced high in the sky. They are contrails of jet aircraft. They’re actually long, slender clouds. Other men are finding them especially fascinating because the theory is being developed that those long, white lines may be changing our weather for the better. Details from Roger O’Neil.
ROGER O’NEIL, reporting:
The exhaust from jet engines, usually seen as long, thin trails of white clouds behind high-flying jet airplanes, may be a big reason why there are 30 fewer days of sunshine a year in the Midwest now than there were in 1900. The daily range between high and low temperatures has also narrowed. Weather researchers, studying cloud cover in 10 Midwestern states, found a sharp increase in cloudiness with the increase in commercial jet travel, particularly in the main East-West jet corridor, there were even more clouds. A jet produces a contrail or cloud because its exhaust consists primarily of water vapor.
RICHARD SEMONIN (Illinois Institute of Natural Resources): In the absence of natural clouds, given the correct atmospheric condition, jet aircraft in high frequency can almost completely cover the atmosphere, visible atmosphere, with clouds.
O’NEIL: Semonin says, unlike most changes in the atmosphere caused by man, this one is beneficial. Clouds help farmers in the Midwest by blocking the sun. Temperature extremes can damage plants and speed up the evaporation of soil moisture. In the Winter, city people benefit because clouds act as a blanket, preventing warm air from escaping into the atmosphere. No one is trying to make clouds now using jet engines, but this study suggests that jet travel is inadvertently making our days more cloudy and some day, weather researchers may be able to use jets on purpose to change our weather. Roger O’Neil, NBC News, Champaign, Illinois.
The paper and TV coverage was also accompanied by some press coverage, such as this piece from the Washington Post, reprinted in The Gazette, of Eastern Iowa, Vol 98, Number 352, Friday Dec 26, 1980:
Very interesting that this trend of contrails affecting the cloudiness has been observed since 1952.
Interestingly there was a similar report in 1998, with Brian Williams. NBC Evening News, Jul 27, 1998. I’d love to see the video of that.

Here’s another from 2006

Strong argument against that “1997″ claim. I’m just afraid that chemtrail proponents will cherry-pick the last sentence of the commenter …
too bad they didn’t actually film any persistent contrails…but still a good bit of “evidence” to the contrary meme…
but of course, it is the “MSM” and subject to the PTB…and could be hologrammed/photshopped/timetraveled back to rig the propaganda…
just sayin
Wow, this is a really big find.
Yes, I was pleasantly surprised to find it. More and more stuff is coming online all the time. So it’s always worth doing new searches every year or so.
This is a very useful tool in debunking the “they didn’t used to do that” aspect of chemtrails. Spread it around.
It’s good in part because it’s nearly impossible for even the most ardent conspiracist to claim it’s a fake. Roger O’Neill still works at NBC 31 years later,
And there are people who actually remember watching this broadcast.
Ya this is a neat find. I will say that I would be leary about stating that persistent contrails/man made clouds are 100% beneficial. I am an environmental scientist and in my experience, any man made change to are environment (deliberate or not) has had very few long term benefits.
This site is funny for me because I know that contrails are just water vapour frozen. However each contrail does represent a huge amount of CO2 emmisisions which I am completely against. So while I know the goverment isn’t secretly spraying us, I do agree with chemtrail people in that it would be nice to see less of them (well just less jetliners – contrails are really the only way to see them up there).
Nobody has tried to say that trails are benign, just that they are not secret government actions to sterilize/kill/hide planet Nbiru/disguise aliens (pick current theory).
The TV report and newspaper article does actually say that it may be beneficial – but purely in a financial manner. With less crop damage, and reduced energy usage.
Perspectives were a bit different in 1980. CO2 emissions were not such an important issue then.
This obviously (like all mainstream news) is a bought and paid for BS new report, using the talk of ‘contrails’ to cover up the actions of geoengineering. I want facts! Not a news report. My own eyes can see the difference between a contrail and a chemtrail. And the ones leaving chemtrails are not commercial jets, so what the hell are they doing up there besides wrecking the skys for all astronomers? Oh that’s right, they are dropping Aluminum, Barium and Strontium. I forgot. They are poisoning us. But hey, thanks for trying to debunk something so catastrophic! You better be one THOUSAND percent right! OR ALL OF THIS IS ON YOU!
There must be something better you could do with your time, rather than helping people who are scared and angry about chemtrails, when your not exactly sure if they should be or not…?
What is the difference between a chemtrail and a persistent contrail?
