Listened to the tape seemed fine to me.....the first thing nippon said was they had to stop. Nothing of fire but when ATC repeated directions only then Nippon said they had a fire. After that, it took a while for Nippon to respond to ATC challenges of declaring emergency and fire services queries....ATC cleared EVA to land and directed further exit to avoid Nippon.
Finally Nippon answered ATC and said yeah request TAxi and wanted to continue on their merry way since checklist put fire out - fire out-fire no more....nothing wrong....dumb asses. ATC made them stay put while fire services already been called for by tower to check them out.
From listening to it seems Nippon distracted by doing checklist but not much other thought into anything else....ATC seemed to right on top of it.
