If two aircraft come together in controlled airspace there has been serious, most probably serial/multiple, human failings but its not a system design fault.
Is this why you don't want to classify the airway corridors into
Orange and the
Canberra terminal area after hours as class E?
You controllers can rest easy about these RPT near misses can't you, as they happened in class G. Not your responsibility is it?
What public position will you Class E deniers take had these RPT incidents resulted in fair paying passengers deaths especially when families are told it could have been avoided by implementing Class E back in 1995?
