There are plenty of accidents out there that point to the need for improved skills and better training all around.
While it may in fact be the case that these crews were under trained, these are cases much bigger. All pilots have human brains and we are all subject to the same or similar cognitive limitations as these crews. These accidents are a window into how a human pilot (any one of us) process information and makes decisions.
We best pay attention to what they are telling us.
