For an airline that fly in some of the worlds worst flying conditions I think that WF have at the very lease an acceptable safety record when the mountainous topography, short slippery runways, drasticly changable weather and lack of diversion airfields are taken into account.
I suspect that most of the flack above is from those who spen most of their time flying radar to ILS in the very controled environment of Northern Europe and never operate from slippery runways.
This having been said there is always a need for an open safety culture as covering up incidents never works in the long run and just makes it look like you have something to hide.
