Let's just hope that when the investigation really gets underway that the fleet managers tell the truth about the constant interfering of senior management on who gets what job and who passes tests that they have really failed.
IMHO this interferance is the very start of the holes aligning.
We all knew it was occurring but nothing was ever done about it. We all knew there was an accident waiting to happen and and now it has. Will it be the last? Not if the current interferance continues.
Maybe, just maybe if people tell the truth there is a chance, but I doubt it.
