Can't help thinking that all this "won't ever happen" ignores the facts of airline ops today. Most crews are encouraged to engage the Autopilot at 600 feet on takeoff, couple it to the FMS and down the ILS via a NAV to NAV transfer to DH (which could be right to touchdown). Add Synthetic Vision and/or Enhanced Vision with pattern recognition like the DARPA trials vehicles (a much tougher test than landing straight ahead or taxiing in) and you're there. Probably doable for much less than the half a billion euros quoted.
