if the aircraft had been a hundred yards or so left or right of the course they tracked, there is a distinct possibility that they would have passed Black Rock in complete ignorance of the danger it represented.
That is a bit harsh.....but had the Aircraft not hit the Rock and been destroyed....there would be no report and we would not be having this discussion.
Had the evasive maneuver been successful....there would probably have been an Incident Report of some kind and in all likelihood some soul searching by the Crew about how close they came to disaster.
We cannot think about what might have been.....as that is too late now.
Seeing a very honest inquiry into this tragedy that results in some serious Lessons Learned that work towards preventing similar events in the future is what matters now.
Otherwise....four very good People died for no good outcome.
We owe it to them to see that Review takes place.
