From the thread on the failure of the IHST:
Sikorsky safety specialist Steve Gleason summed up the data-driven conclusions: "We're not finding new ways to crash helicopters. We're just doing the same thing over and over."
Isn't that a good reason for better design rather than OEMs just sitting back and hoping that Darwinian selection will make pilots more error tolerant but in the meantime sending arrogant recommendations to their customers to do better?
