The classic CFIT CRM breakdown was some years ago when the Flying Tiger 74 crashed short of the runway at Kuala Lumpur.
None of the three crewmembers had questioned the misunderstood ATC clearance to: "Descent now TWO four zero zero feet."
It was interpreted: "Descent now TO four zero zero feet." If the crew had checked their NDB approach chart, it would have alerted them to the fact that descending to "four hundred" (400) feet was suicidal.
Even when the GPWS sounded ...at least five times, this tired crew had continued the approach...into elevated terrain.
