The 777 was towed off the runway about 45 minutes ago. Rwy expected to have been reopened about 15 minutes ago (18:30).
One poster on another forum looked at the flight tracks. He said it looks like they veered left off the runway, then right and then went off on the grass on the right side. Quite strange...
At the time of landing there was CAT II/III. Fog was lifting at the time.
