The Earth's atmospheric dome is more than enough to bounce signals from one point to another, allowing trilateration of a receiver to be achieved. This just illustrates yet again the explanatory power and effectiveness of Flat Earth Theory. Equally valid and compelling explanations exist for the phenomenon we see. You dont need to keep your mind stuck inside a sphere. Forget science. Try THINKING for yourself in a free and unrestrained way. You might be surprised at the results.

Ok Krish, stick with me here. If you get on a plane in Charleston, South Carolina and fly to London, England, you fly east. Then you fly to Hamburg, Germany. East. Then you fly to Tokyo, Japan. East. Then you fly to San Francisco, California. East. Then you fly to Charleston, South Carolina. East. Ok. You flew in one direction, and got to the same spot. You flew around the earth. It doesn't even take science to debunk flat earth theory. Just stop.
