WOW! That’s extraordinary. I find that the flights to and from Asia are always much more bumpy that those from the West Coast to Western Europe (which is what I’m flying now).
We’ve hit significant turbulence twice, once approaching Taipei and once leaving toward Tokyo. It was on Eva and warning was timely and the attendants were seated and no one was hurt, just scared. Once we had only five minutes warning, the other time ten. After we landed in Taipei we looked back at the sky to the north and there was a huge storm with absolutely black sky under a shelf of clouds.
