Is he still working in aviation, maybe he would like to be a "whistle blower" Let us know whats up..
You'd probably react much the same if your son kept going on about fairies living at the bottom of the garden!
Aircraft are believed to be responsible for 2 to 3 percent of human CO2 emissions. Like other high, thin clouds, contrails reflect sunlight back into space and cool the planet.
However, they also trap energy in Earth's atmosphere and boost the warming effect, the study says
Contrails are artificial clouds that form around the tiny aerosol particles in airplane exhaust.
They appear only in moist, very cold (less than 40ºF/4ºC) air—usually at altitudes of 5 miles (8 kilometers) or higher.
Some contrails can last for a day or longer, though they gradually disperse and begin to resemble natural clouds.
"The jury is out on the impact of contrails," said Patrick Minnis, an atmospheric scientist at NASA's Langley Research Center in Langley, Virginia.
This makes a case for contrails being harmful, but it doesn't fully grasp the entire problem, I have personally witnessed the grid making by the same planes going back and forth in one area a few years ago and then leaving a what is referred to around here as a "sundog" and it was a very warm humid summer day in Missouri. The research above says cold is a factor and the planes were not high enough in the sky to be as cold as the criteria requires for the contrail.

Every engine releases particulates fancy name for emissions. You car produces emissions as well but to say that its a secret organization or government plot is silly. Until we get away from burning fossil fuels there will all ways be an impact on the environment just how much of one is the question.

So where this this chemtrail belief original from that if some planes are going north/south, and some are going east/west, that it somehow means a grid and spraying?
Are you saying it was warm at 30-40 000 ft? How warm do you think it was?
Obviouisly if you had sundogs up there, then it was favorable for contrail formation. I think I just need to go run into a wall a few times headfirst, I think I would have more progress at times.

How many airline pilots are ex mil school boy ? If they are ex mil there is no exit from official secrets .They are bound for life .
Nice try but as usual the armchair experts are blowing smoke to crawl up the ladder .
I dont need to keep a log (ho hum) . you guys and your 'by the book' professional banter !
And as for that wetdreamliner , its just a desperate attempt to make up lost ground to the new airbus , the CIA having failed to sabotage it like they did concorde .
Carbon is notoriously brittle and has poor shock absorption . Rolls Royce went bust trying to make carbon turbine blades work.
The real future is titanium alloys ,which america does not have any hard cash left to purchase on the open market . The Russians on the other hand have #loads of the stuff...
American aerospace is going down the toilet due to arrrogance ,greed ,incompetance and a chronic lack of homegrown talent .
half the reason for overreaching in Iraq was to save the defense industry from its own incompetence .
most all off their aerospace tech is stolen form russia and europe because they can never figure the hard stuff out for themselves .
The vaunted raptor is in fact over twenty years old , the design again a rip off from a foriegn power . Its been a disasterous failure in operations ,which is why 'officially' its still in the testing phase .

My Dad was fairly high up in civil aviation and he would get very twitchy whenever I mentioned chemtrails to him. I used to bring it up from time to time, and tell him there was a massive difference in contrails starting about 1997. He would flatly deny it and even get irritable, which I thought was pretty strange considering he loved to talk about other aspects of the industry. Maybe he knew something was up.
He used to dislike the highest manager types, thought they were corrupt. And I remember once he made an offhand comment about some of them being involved with Mi5, but never mentioned it again.
Just one of those random, proofless stories.

I am trying to be open to all angles of this problem. And it is a problem, is it not?

When our Recon unit was formed just before ww2 , we used a civvy lockheed electra for all our illicit photo recon work. MI6 paid for the aircraft and we flew out of Hendon (and off the record ,Croydon too) Our Wing commanders cover was as so often is the case , 'businessman' .
