I'm not going to comment on the flying aspect here, as I only fly privately. What does shock me though, is this para from the report:
The ATC Tower controller and the Approach controller were discussing that the aircraft’s approach was not in accordance with their noise abatement procedures and that a violation would be unavoidable.
I mean - really? Two ATCOs watch an Airbus fly towards a ridge and all they think about is noise abatement? Methinks these people haven't quite understood their roles. Scary.
