If I read this right, QF's 747/RB211 IPT uncontained failure is because "Qantas push 'em hard". Is this an acceptable way of life in the commercial airline industry? If engines are run within certified parameter limits, how many uncontained (read shrapnel) failures should be expected?
In my experience in the industry, the only acceptable number was zero, and a huge effort expended toward this goal. "Pushing them hard" was NO excuse!
