I find it odd that all these idiots who say these chemtrails are to save the planet and reduce globalwarming have forgotten the fact that each 747 take off is equal to 2 million lawnmowers running for 20 minuites.Thats just the take off.Everyone who lives around chicago O hara airport are starting to report cancer.And this is just from normal exhaust.These planes heat up the atmospere and pollute it like the worlds never sseen.And people are worried about hair spray.Check out endtimesevents.com/CHEMTRAILS.html
