Just think of what an anti-terrorist arrangement it would be to have planes controlled from the ground or sky.
That would be great. Until the bad guys figure out how to hack or jam the signal.
Ground-based transmitters can be sabotaged. Satellite signals are EXTREMELY weak compared to the RF comms we are used to using in aviation...localized jamming is not too hard.
Anti-jamming methods exist, but they are cutting-edge military technology, ie classified and expensive as hell.
