To be honest I really don't know what they are. But one day I searching Ratdog + St. Louis videos on youtube and the video that I posted is the first one that popped up. I gave it a watch and tried to do a little research after watching it. And now I realize I see the damn things outside all the time.
Apperantly they are sending these special planes up in the air to make certain patterns and the trails they leave with the patterns expand so in a few hours you have a blanket covering the sky (which could easily be mistaken as clouds).
Some people believe "they" are controlling the weather with the chemicals they put in the air. Some people "they"are trying to control population. There are also claims that these so called chemtrails are giving us respiratory problems along with a few other serious health issues.
These were taken outside my house a few months ago..
This was taken outside my work today...Every day I go outside at work they are marking their X's. I'm kinda tired of it!
Great video of Chemtrails in the St. Louis area with some Ratdog music in the background. This has some great footage. It shows the patterns and it actually captures one of the chem planes and a regular airliner. The airliner is not giving off any trail but the chem plane is... eye opening! Its a little long but worth the watch if you are interested in this stuff.
