From the November 2004 Idaho Observer:
The photo above was posted to a NASA website October 13, 2004. NASA explained how "contrails" are "cirrus clouds created by airplanes."
NASA mentions the formation of ice crystals but does not explain the presence of particulate matter in these man-made clouds. The space agency does, however, reveal that the effect of contrails (what the more discerning refer to as "chemtrails") on the climate is "...a topic of much research."
Though the space agency does not come right out and admit that the contrails contain chemicals that do not disperse like simple frozen water vapor, NASA does admit that something is happening to cause changes in our atmosphere. According to NASA, "[Chemtrails] have become more than an oddity-they may be significantly increasing the cloudiness of Earth, reflecting sunlight back into space by day, and heat radiation back to Earth even at night."
Independent researchers have found "contrails" to contain measurable amounts of aluminum, barium and other toxic compounds.
It has also been noted in reports from all over the world that hospital admissions for upper respiratory distress increase after events such as those pictured.
This NASA photo taken October 13, 2004, shows significant chemtrail coverage in the skies above the southeast U.S. NASA admits that "cirrus clouds created by airplanes may be significantly increasing the cloudiness of Earth." If those hundreds of man-made clouds contain elements of known toxicity, then it is logical to infer that more than just the weather is being affected by them. ~NASA photo
