From the Crikey article;
The RB211 engine issue highlights the need for Qantas to consider more than theoretical savings in decisions that affect operational safety and reliability.
This is 100% true but...... if you are paying your managers huge bonuses to cut costs in their own areas of the company you will never achieve it. The head of engineering who signed off on the closure or reported that it wouldn't affect safety to the board, won't give a stuff becuase he/she has already bought a new Mercedes with that years bonus.
They probably don't even understand that the error chain to a hull loss often starts years prior to the accident with a management, decision.
