Interesting article...
Goes to show:
1. Aircraft need airframe strike protection (tail as well as wingtips or engine nacelles). It might be a good idea for Airbus to integrate an attitude limiter below a certain radalt -say 30 feet e.g.- into their control laws. But I can imagine that would be hard to certificate since you need to protect it well against radalt faults (wouldn't want the attitude to be blocked to say 10 deg pitch/5 deg bank during a GPSW/TCAS avoidance manoever.)
But there could at least be a warning when you're reaching the limits.
2. Basic flying skills are still of major importance, FBW aircraft or not. Seems the strikes on the 321's where the result of an approach gone wrong. Why didn't they go around? Having said that we're all only human beings so there are those who have and those who will... But nevertheless more attention should be paid to basic flying in all levels of training.
