IIRC the Heathrow incident resulted in tragedy. The captain claimed that the aircraft had aligned itself with the Bath road during the approach which was the reason for the mistake. Despite this he was held responsible and was suspended. This affected him so much that he eventually committed suicide. Some time later the same aircraft did exactly the same thing again.
In Singapore in the 80s, Paya Leber was the international airport but RAF Changi used to have its fair share of inadvertant arrivals. Lufthansa was the main culprit.
