1963 - A color guide to Clouds (contrails)

From the book "A color guide to clouds", published in 1963:

"Contrails persist when they are formed at a sufficiently low temperature for them to become frozen before they evaporate. Then because of different winds at different levels, they may be spread over the sky to form a layer of artificial cirrus. Sometimes the air is sufficiently dry for the ice cloud to evaporate in ten minutes or so; but often it may last for several hours"

interesting that they did that back in the 60's... i bet there are a few more books out there, wonder what the news was reporting any strange changes at the time, or if people remember any changes in the skies then.

The point is that these are just contrails, both now and in the 1960s.

If it has always been like this, then why do you think it is "strange"

the only thing i believe in is that chemtrails are real, and every day chemical planes fill the atmosphere with bario and aluminum

THEN SHOW THE TONS OF EVIDENCE! Words are nothing without action you ignorant fool!

(This was in reply to someone. Great video. Chemtrail believers are just unreasonable)

I think people need to learn about aviation & contrails before jumping onboard the chemtrails bandwagon. The idea that contrails can't persist for long periods of time is ridiculous. They are basically just like clouds after all

@buio20 ..and that this book in this video is fake!

[TIX74]

I Think this book is faked....why the right pages are light blue and pictures on them seems to be attached with glue on the page? MMMMhh... suspect!!

i love the people who say" i remember from when I was a kid)

i remember a lot of stuff when AI was a kid...doesn't mean it was 100% true.

could you see any "child" today taking his backyardigans backpack out to the park and getting out his thomas the train pencil and book, and documenting the skies....lol

i remember from when i was a kid....you MUST laugh at yourself for such a silly remark

[CTYForg]

my chemtrails NEVER dissapate/evaporate...sorry.

There is more than just water in em.

[Airclot]

YOU are unreasonable. He has provided names of books that clearly state contrails have been around since forever, and all you can muster is that you "remember" them to be smaller?

[Epoxynous]

What routes do the planes fly on that you don't think are commercial routes?
