I think Ayu has got to be safe when flying out of Narita, because recently on February 20th a Northwest Airlines 747-400 just went for a bumpy landing and caused around 50 people to get injured... (see

Hopefully Ayu and her other passengers on her flight stay safe and does not get any aviation-and-weather-related injuries during her journey...
