Agreed barit1,
Although my airline is a large carrier in South America, we have had something like 2 or 3 planes take evasive action in the middle of the night for conflicting traffic at the wrong altitude. I know TCAS saved one double widebody collision, another saw another A/C at night sans lights at the same altitude.
We've operated many flights down there, there but I don't think we've had 600 million flights in the 75 year history of our airline worldwide if we use the "experts" methodology.
Those were misses. The hit rate was 'speculated' to be 1:200 million.
