I would be interested to know the exact metar report.

Absurd conditions..they really should have just closed the airport. As Al mentioned, with every plane carrying hundreds of lives and tens of millions of $$ worth of machinery, it makes no sense to be taking chances like that. Think of what must have been going through those passenger's minds in the Etihad (expletives abound)!!

 

I've dealt with Narita during bad wx systems, but this takes the trophy!!

 

If the winds are being reported below the aircraft's and SOPs maximum and they feel comfortable to give it a go then they can take it in. Obviously it wasn't too windy or else they wouldn't be taking it in. In the video it looks like the difficulty is in the changing gusts and not the sustained winds.
