All of this is ABSOLUTE NONSENSE!
All of the incidents you cited about the 777 being unsafe involve problems with the ENGINES, in particular, the Rolls Royce Trent 892 engine, which powers the Singapore and Emirates 777 fleets. The Trent has had problems lately, however, these were all minor incidents of contained engine failure and in no way posed any dangers to passengers on the plane. GE90 and Pratt & Whitney powered 777s do not have problems. It is silly and ignorant to avoid the 777 and deride it as a bad aircraft just because Trent-powered 777s have had problems- I suggest you slander Rolls Royce instead.

And the comment about 777's selling well only due to political pressure is also nonsense. Do you have any facts to back your statement up? Nope, because airlines buy the 777 because it is far more efficient than the A340 and performs far better (not to mention a much more superior interior design as compared to the A340).
