Pukin Dog, you really are losing credibility very quickly!
Maybe you could comment on this situation...
Aircraft on approach, 10 mile final, been cleared to land despite poor vis, despite 3 aircraft ahead. One of those 3 stops on runway for whatever reason. Aircraft on approach continues. 30 seconds later he is told to go-around due to blocked runway. Now, what would happen if that a/c had had a comms failure, or missed the go-around instruction? He'd land (as cleared). Potential disaster... How is this a good system?!
