No, it is your selective understanding of the facts that makes you different. What is it that aircrafts need to overcome in order to stay airborne? What is it that prevents aircrafts from reaching escape velocity, or entering outer space? You ignore the fact that every aircraft has a ceiling limit(less air, less lift, less oxygen, less thrust). You ignore that all planes have longitudinal static corrections, which means pilots don't need to make corrections. You completely ignore or understand the underlying science behind all plane's Inertial Navigation and Global Positioning Systems. You ignore the overwhelming effect that gravity and the spin of the earth has on the plane. Finally, a stable flight always includes maintaining the balance between Gravity and Lift, not simply traveling in a straight line.
Maybe you can answer me this? The earth is spinning(flat or spherical) at 1000mph, and the speed of sound(flat or spherical) is 770 mph. If I were standing next to someone near the edges of a flat earth, would I be able to hear any sounds either of us could make? You most certainly may be able to substantiate your claim that the earth is flat, but definitely NOT by using any unbiased objective interpretation of the facts.
