In Asia, you have a fondement culture teached formally to each one student from the kindergarden to University: "The boss is always right"!
No one student ask a question to the teacher, never. Why ?
1/ if you ask something, it mean you don't understand = you loose the face
2/ if you don't understand it mean the teacher don't teach you clearly : He lose the face...
And the most important in asia, before all is : Never lose the face....
Not only in helicopter industry or army, all fields included Civil aviation. Many of the crashes are due to "Yes , boss" culture...
It's not mine...
