It is interesting to see the difference in response between here and in the USA.
In the USA there may be speculation by news organizations and their "experts" about the cause. There is usually no speculation about blame as the Transportation Authority will decide that. And, considering they will take every minute piece of the plane and reconstruct it in a large hanger, they usually find the exact cause.
I was surprised, when reading the local papers, how blame was instantly pointed at other people. "Your fault." "No, your fault."
But, like Kipling said, "East is East and West is West, and never the twain shall meet."
The West is based on the Judeo-Christian idea of "truth." ("You shall know the truth and the truth shall set you free.") No matter how important you are, if you did wrong, you are wrong.
The East is based on "Face." That is, it is based on where you are compared to others. You don't have to be right; just higher than others. Hence, the caste system and its descendants.
Fascinating.
