There's also a program for low-level chem-trailing. Can't say too much about it, but I operated deep cover in a local low-level chem-trailing organisation some years ago. Here's one photo of a typical low level application run.
It's been found that very high levels of di-hydrogen monoxide can increase the number of breasts on chickens. This photo was a test run for a large poultry company interested in this genetic modification, potentially increasing their chicken breast output by 400%. It was of course a stunning success.
The "stratospheric" chem-trailing program has been known for some time and has been a major success. The world is now dumbing down at the required rate as stipulated by the UN WHO. Fluoride was found not to be as effective as first thought, hence the move to di-hydrogen monoxide - far more potent! It's only very recently that the low-level/high concentration chem-trailing program details are coming to light.

Seen some years ago - 2007 I think.

I think I've said too much!
