Latency between the jet and the pilot is an insurmountable problem. You either have a very laggy connection to a human pilot who is far away, or a wireless link to a more local pilot who is vulnerable due to being in a combat zone. Plus, it creates an EM signal that could be disrupted as a tactical weakness. The latency, though, would be the primary killer. It's why the Air Force still needs to send drone pilots to Afghanistan - you can have a person piloting the drone during the mission out of a container in Nevada, but they don't have enough reaction time to safely and reliably land the thing in Afghanistan. Control has to be handed off to a local pilot who has a lower-latency control link to the aircraft.
