So VOR's were supposed to be phased out what, 10 years ago, and they're still around. The C-17 is a pretty advanced aircraft and we STILL can't shoot GPS approaches and we (military) own the entire system. For pete's sake we still have NDB approaches. There are way too many situations that arise on every flight that need a human to make decisions. I'd really like to see some desk jockey put a 500,000+ lb. airplane down on a 3500 X 90 ft runway. It's a LONG way off.
