High bypass turbofan engines became common in the 90s. They produce more contrails, and more persistent contrails at lower altitudes than low bypass turbofan engines.
Those engines should be better regulated. They are causing a disturbance.
How do you suggest that should be done? They are more efficient and cause less pollution, but they do generate more contrails. So something has to give.. you want the old engines back? Something like an A380 couldn't even fly with the old engines.

About Rosalind Peterson
So, this woman...isn't really anything different than your average conspiracy theorist...
Ms. Peterson was a Keynote Speaker at the 60th Annual DPI/NGO Conference on Climate Change (New York on September 5-7, 2007.) She spoke about agriculture and the negative impacts of experimental weather modification programs on tree and plant health, along with other important issues. Since then she has presented her United Nations Power Point Presentation to colleges, universities and interested groups. She has also been interviewed on numerous radio and television programs. (Scroll to the bottom of this page to see a portion of her Keynote Presentation.)
In 1995, Rosalind, now retired, became a certified California United States Department of Agriculture (USDA), Farm Service Agency Agriculture Crop Loss Adjustor. She worked in more than ten counties throughout California. Many crop losses throughout the State can be attributed to weather related causes. She worked for five years for the Mendocino County Department of Agriculture as an Agriculture Technologist before being hired by the USDA Farm Service Agency in Mendocino County, California.
Rosalind has a BA degree from Sonoma State University in Environmental Studies & Planning (1991 ENSP), with emphasis on solar power, photosynthesis, agriculture, crop production, and the efficient use of energy in the future. Ms. Peterson has won several awards and recognition for her extensive efforts to protect drinking water supplies in Martinez, California, from toxic chemical contamination. She also writes articles on many subjects including protection of the environment from ongoing, unregulated, atmospheric geoengineering experiments and weather modification programs
If she thinks HAARP controls the weather, than I don't care what else she has to say, she clearly doesn't understand basic scientific principles. Considering HAARP is decommissioned and all..
Where is the documented proof? Just her say so?
lol

Contrails are a party of air travel. They were here from the start of aircraft flight. The first contrails, including persistent contrails were seen during WWI.
The only way to stop them, other than flying lower, which would increase the cost of a flight because they'd burn more fuel, is to inject a suppression chemical into the exhaust.

Actually they have. Contrails are just cirrus clouds so there's no reason they wouldn't.

As per usual.
Let's put a deceitful headline on the post and misrepresent the facts in a way that allows "headline-readers" to go forth and spread yet another lie.
Shame on OP.
If it was allowed to say you were an i.....
Whoa. Wait. It isn't.
So I wont.
.
As others have said more or less clear.
Let's focus on the pollution caused by people who have enough money to spend, so they can go places they don't really need to go.

I'd love to see that pic. My initial research just now into High bypass turbofan engines seems to imply that they are far less likely to create contrails due to being more fuel efficient and having a relatively cooler exhaust than a standard turbo fan engine. I'm still looking into this however, so I'm reluctant to draw any immediate conclusions. Info I'm looking at right now is here: High Bypass Turbofan Engines Cannot Produce Contrails

The cooler exhaust is exactly WHY they produce contrails. They push cool most air around the core, which interacts with the moist air around it. When the air around the engine is near the saturation point, the air pushed by the engine tips it past that point, and you have a contrail.

hmmm-did you read the pdf document on the link I provided? It seems that the author's viewpoint is in direct opposition to your statement. More research is needed on my end before I comment any further, but please, feel free to refute his info.
