Chemtrails and climate engineering

[Cybele]

Officially, the “chemtrails theory” is considered to be a conspiracy theory. The line-shaped clouds left behind aircrafts are nothing more than condensation/vapor trails composed primarily of water, in the form of ice crystals.
A team of members from Geoengineering Watch acquired a NOAA flying lab and tested at altitude, to confirm the elements that were showing up at the surface. The team carried out multiple sample gathering flights in the high altitude haze layer being emitted by large jet carriers. The elements found in the trails, were similar to those listed in climate engineering patents and surface tests of precipitation from all over the Globe. For example: aluminum oxide. These nanoparticles have a high toxicity for the environment and human health.
What is your take on it? I remember when I was looking at planes in the sky as a child, almost all of them were leaving a white, thin, relatively short trail, which would quickly disappear (in 15-20 seconds maybe). I am 100% sure I remember well. These trails were never forming patterns like a grid, or foggy looking "clouds" .
