- er, no, unless you drop from the poles. The Earth rotates, and you start out moving east with a velocity of cos(latitude)*465 m/s with a specific angular momentum of approximately 3e9 m2/s. That angular momentum corresponds to a perigee radius of around 260 kilometers deep inside the "reduced gravity" core of the Earth.
