And what happens if the remote control (or the computers controlling it) fail?

well, with them flying over commercial traffic (now), I'd hate to think ... I just hope they know what they are doing ...

Same thing that happens in modern fighters where the flight controls depend on computers to work, they crash. Only there's no pilot to get killed. In a modern fighter if the computers go Tango Unifrom, so do the flight controls.
