Thank you for your attention, my friend...check this:
You are talking about condensation tracks from planes... those
are only possible in very high heights, because condensation appears
with great temperature differences.
I can see the passanger planes from Berlin Tegel from my balcony and
you see nothing! coming out of their hi jet engine.
This is your next homework ;) because "Hi jet engines"
don't cause any exhaust gases that you can see...
Uups ;)
These fine layers of metals are being used in combination
with Haarp and other Antennas (that are not only used for Mobile
telecommunication) to heat up the molecules in the atmosphere,
to then e.g. manipulate weather, thoughts....
No conspiracy. All (bad/evil) science...
I will add a Patent to my Post.
I research Patents since 20 years ;)
Peace
