The question was not "why is this impossible?" but "why didn't someone remote control the GW flight"? Because, although all the required technological pieces are currently available, remote control is not actually implemented in any commercial aviation aircraft. As to "why is it not implemented" - because it would create far, far more problems than it would solve, without a measurable benefit.
