Thank you so much, 'Engines', for this view from the coal face.
It is another illustration of the rot in Boeing's formerly preeminent engineering culture.
When management is seduced by 'Powerpoint Engineering', stuff like 'all the risks materialized' is to be expected. Nobody dares ask the hard questions early.
As shown by the KC-46 or the SLS capsule, Boeing reliably does a poor job of detail engineering, but the marketing remains world class.
