Worse still are those who say "they're weightless because there's no gravity" Smile

An orbital body still has weight and is falling. The reason it doesn't hit Earth is because the horizontal component of its trajectory is sufficient (7.9km/sec) to make the trajectory the same as the curvature of the Earth's surface. In other words it keeps falling in an arc but the Earth's surface curves away at the same rate. (So much for flat earthers!)
