Why do the planes keep coming back? Again and again.
When they started years ago, nobody thought anything about it. A plane would fly over and the long white condensation trail would stream out behind and disappear a couple of minutes later. These white trails were water vapor, and they called them contrails for short. But then things changed. The planes came more frequently. They made patterns across the sky. Some days you could count a dozen contrails across the sky, but these contrails did not disappear, they persisted, sometimes for hours.
Then the reports started coming. People complaining about their health. Scientists finding unexplainable chemicals in the atmosphere above and the soil below. Crops failing where they used to grow abundantly. The planes could be seen in the skies all over the world, along with the exclamations of "Conspiracy theory!" Instead of contrails, they started calling them chemtrails. It's up to you to decide what's real and what's not, and the fate of the world could hang on your decision.
When you google the word chemtrails, you get results that would make for a great science fiction movie—the images you google raise questions too. Are chemtrails real or crazy, a global conspiracy for climate control or simply persistent condensation trails? And why do the planes keep coming back again, and again? What do you think?
