This is a case of Press-On-itis. Come on folks, how many CRM refreshers have we sat through to know that it's our responsibility to speak up and do the sensible thing. If ATC haven't temporarily closed the airport and you get down to 500ft with winds and turbulence like that then surely a go-around is a reasonable course of action.
By that point you've looked at your fuel status....you know how much fat you've got to hold overhead before buggering off up the road to you Alternate.
This just seems a classic example of all the holes lineing up resulting in a bent airframe and about 300 personal injury claims!
