From the "intynet" so must be true:
Chemtrails, an Introduction
It is being reported that people with average or below average immunity are experiencing pneumonia-like respiratory symptoms, while people with stronger immunity are only experiencing slight discomfort for a day or two or no symptoms at all. Some people have gotten very ill and the symptoms seem to keep returning after a short period of improvement. It's possible that some of these sprayings might contain special bioengineered pathogens designed to affect only certain racial groups.....
...........including low level population reduction mind control and/or tracking, and to foster weakness and apathy among the general population in anticipation of the New World Order takeover agenda which will likely include the imposition of martial law (a sickly population is a lot more controllable and compliant than a healthy, vigorous one).
