I sat next to a window for over two years watching jets leave these things in the air almost daily. They are definitely not natural formations; Not even close.

I've been alive for 44 years now, and never before 2005 have I experienced the appearance of strange "clouds" that burned my sinuses so badly that I had to take action, not to mention the salty-metallic taste in the air.

These "strange" clouds that come from jets (I'm a first-hand multiple-event witness) are accompanied by burning sinuses, cracking joints, liver pain, joint pain, fatigue, dark circles under the eyes, muscle pain, headaches, swollen sinuses, burning eyes, salty-metallic taste in the air, and more.

These symptoms can all be directly related to mercury, aluminum, and barium exposure, exactly the things that multiple independent tests show these "strange" clouds (that come from jets) contain.

Science is a process of observation, and all of these observations provide repeatable corroborating evidence.
