This flight had two starts. During the first one, halfway its run to the air, two loud bangs could be heard. This was immediately followed by the pilot's action to brake the airplane and stop it aside the runway. A short while later it was announced that one of the engines had a problem and that all passengers had to get off again. What followed was 4 hours of waiting on Tokyo's Narita airport for information (at least in English), queuing for the complementary lunch and finally boarding again for the second start in another airplane, fortunately. That one was succesfull.
