Dick, surely any airport where an aircraft of 717/ 146/ 737 size operates should either have a manned tower with radar coverage, or at least radar coverage tied into TAATS with control/advice from an operator.
(Maybe someone should also come into modern times an install some new navigation equipment at these aerodromes too, but thats another issue, and if a major international airport like YMML cant have an ILS on 34 then what hope do these others have!)
I think radar coverage will happen - but only after a light a/c has plowed into a 737. QANTAS certainly won't demand or pay for it. Qantas only reacts after the fact. The government wont act either until thepublic demand it. So unfortunately what we need is a prang to bring about change. Touch wood a prang doesnt happen.
