I don't think anyone is suggesting that yukky stuff doesn't ever happen on western airlines. I have personal knowlege of far more incidents and cover-ups on a UK carrier than any ME one, yet I can fully understand the difference between a cultural tendancy and oportunistic endeavers of some western individuals and organisations.
Nobody should be talking in absolutes, just as isolated examples are not going to prove a general case. Cultural tendancies will tend to influence, they will not make every incident predictable. I am worried that so many people have already decided that they will never hear the truth about the Flash 737. I certainly agree that we are less likely to either hear the truth or have some people accept it, but I wouldn't rule either out so conclusively.
