The early Quantas Flight 32 engine failure [1] was quite severe and the plane was lucky to continue to fly, for instance.
"a turbine disc in the aircraft's number-two engine (on the port side nearest the fuselage) was found to have disintegrated, causing extensive damage to the nacelle, wing, fuel system, landing gear, flight controls, and engine controls, and a fire in a fuel tank "
Nobody had "omitted" documenting flight-altering automation in the training required to dodge certification requirements...
Indeed it's astonishing to think that one of the tasks that lead to safety and victory for an aircraft which is simple (as opposed to the many which are complex) is the single point of this particular failure.
It breaks the most consistent rule in the English language, so no surprise that it trips people up.
It seems that the better a plane is designed, the "luckier" it gets! Strange how that works.
