I'm very confident that the solutions already exist, and it sadly is all about the money.
But, while we're already on the wish list portion of the discussion; who else is stunned that there isn't a remote control override available yet? After what happened on 9/11, and seeing what the military drones can do (remotely flown from under a mountain on the other side of the planet), I'd say this is long overdue as well.

As I said earlier, the satellite coverage would have to be increased to have a comm link with every flight. Also, as the Iranians proved a couple years ago, they can hack a remote control system and take over a drone, and land it in Iran. It would only be a matter of time before some goofballs hacked a remote control system to take over a flight and land it elsewhere, hold it for ransom, sell it back to the owners.
Think Somali Pirates, but taking airplanes full of people, instead of big ships.
