Are you denying that culture has had nothing to do with any prangs?
On the contrary. You may have misinterpreted what was written. Ethnic Culture has been demonstrated to have had significant influence on crew actions and lack of effective action to prevent a looming catastrophe.
For example: Training a Chinese cadet during a 737 type rating he was asked by his simulator instructor what action he would take if on a highly unstable approach and it was clear the captain was pressing on regardless of all warnings from the co-pilot and there was every indication that the aircraft would likely over-run after touchdown.
The cadet remained silent refusing to answer the question. The instructor gave him another chance and said would you consider taking over control from the captain and initiating a go-around? The cadet looked at the instructor horrified and said he would NEVER consider taking over control from a captain under the circumstances described.
That, my friend, is culture and the bane of common sense flight safety. Blind obedience to authority will never change in some cultures.
