Simple videos like this are all it takes to prove that aerosol spraying (aka chemtrails) is being done and it is obviously different from naturally occuring jet contrails. The big lines of "clouds" in the sky are from jets (aerosol sprays), and they stay in the sky for hours. The contrail you see being formed here is dissipating rapidly right before your eyes, just as a naturally occuring contrail should. This is all it takes to shatter the establishment arguments that, "these are just persistent contrails that stay in the sky longer due to certain weather conditions," or, "these unusual contrails causing a concern amongst a growing number of people are simply the result of today's increased air traffic." Think about how ridiculous those explanations are. We are supposed to believe that we're only noticing these persistent trails because there is more air traffic nowadays? And now it is possible for natural contrails, which are water vapor and/or ice crystals to stay and spread out into the sky for several hours? go to www.carnicom.com for archives of years of research, and an excellent documentary: Aerosol Crimes
