WRONG!
Anyone with even a passing interest in aircraft accident investigation understands that rarely does an accident occur where the fault can easily be traced to a single cause.
The reality is that nearly all accidents/incidents are caused by a latent failure of the 'system' and eventually this works its way through to the end user, the pilot.
I am not taking away from the responsibility of the pilots but really, in this day and age particularly, with the high involvement of non-operational management in operation decision making, how can only the pilots be totally responsible for errors and business system failures?
The pilot is an easy scape goat but rarely singularly responsible.
Millerscourt is living in the dark ages with that attitude.
