Let me just get my head around this perplexing problem....
To man the tower at Wagga2 is unaffordable due to insufficient traffic. (not surprising in the fall off in GA and Pvt ops)
A mid air collision under those conditions is.. an accident due unaffordability.? Unavoidability more like.
Someone didnt see someone else
The tower is manned. There is a mid air collision ( as has happened at other towered,manned airports) is this an accident of affordability.? Someone didnt see someone else
Doesnt really make much difference to the victims either way.
A safety issue is not made safer by hurling big heaps of money at it
While most mid-airs occur around airports, some/many years ago the stats then said there was , on the basis of operational hours flown and the number of a/c in Oz, (then when GA was healthy)...the possibility of a collision once every 600 years. Now it must be about 700 years
Most fields around the country dont have towers, and it all seems to work pretty well that way.
Just make sure its not your year! Look, listen, see and separate.
