This is totally retarded. The planet's inertia makes everything move together, including the atmosphere, which is a gas with mass. Everything moves in harmony TOGETHER!!. Your inertia just doesn't stop once you leave the ground. Get in your car and throw a ball in the air. The ball stays with you. The fuck wit who made the video does not understand inertia or understand basic physics. The amount of sheer idiocy is on full display, which is why the people who believe in flat earth are idiots who know nothing about the laws of physics.
