Chemtrails on German TV

I know that the idea of chemtrails sounds a bit paranoid. Yet I noticed as well that most adults, as long as they don't professionally deal with cloud phenomena, perceive nature quite oblivious. After I heard about chemtrails, I simply started watching the sky more than before, and soon noticed strange celestial patterns.

The video below shows a meteorological computer simulation of the weather above Germany and the neighbouring countries. Just watch from the 0:28 to 1:02, focusing on the western border of Germany. Some snake-like trails appear, and look so weird that the weather man tries to explain them:

"Und dann haben wir noch etwas, was wir nicht als Regen oder Schnee identifizieren können - hier im Westen, diese Schlangenlinien. Da haben wahrscheinlich am Nachmittag über der Nordsee ein paar Flugzeuge, Militärflugzeuge, raus gebracht, und in etwa 5 bis 6 km Höhe, das hat mit Wetter so nichts zu tun."

Translation:

"And there is something else which we cannot identify as rain or snow - here in the west, these wiggly lines. These were most likely brought out by some planes, military planes above the North Sea, in about 5 to 6 kilometers altitude. That's completely unrelated to the weather."

Weather is a complex, chaotic feedback system, closely linked to climate. Aerial weather manipulation does not yet work perfectly predictable, however, it is deployed in various areas. It sounds quite bold to claim that artificial clouds that spread over 500 km, stretch about 10 km wide have no influence to the weather. And as far as I know, there is no war in Europe, so why can military planes some shit in the sky? And how did the weather man know that it were military planes?

Freedom and democracy can only exist without military and secret services.
