Chemtrails?

So many jets flew today in the Austrian skies. The Air force must have been having a drill for there were around 7 or 8 jets simultaneously flying towards the West direction. I captured the sunset this afternoon and since the setting back of time to the European winter time last Sunday, the sun has been settling down quite a bit earlier at around 4:30 PM .

This sunset may not be so spectacular today , but I am sure there will be more lovely sunsets coming.

Andalusian Jet Stream....

I took the photo below in Andalusia (Spain) about 10 months ago when Covid 19 started spreading in Europe. The jet streams were sometimes enorm and on a daily basis, it was somehow frightening. Some locals thought the jet streams have chemicals in them to prevent the spreading of the virus. Image Source

As far as the jet streams are concerned, the same drill happens in Southern Spain from Fall to Spring. It is even more often there than in Austria. What about the chemtrails and its conspiracy theory?

Do you think that these jet streams are polluting the Earth? Are they affecting our environment? What is your opinion about this?!I!I would love to hear your opinion on this matter!

Take care and stay safe everyone!
