This tragedy should work to remind us all of the increase in risk that flying in marginal weather creates.
From a few posts it appears the Pilot involved is very well thought of...is considered to very Professional and quite capable. That is how I would like to talked about should something like this happen to me.
As any accident, this event must be examined to determine the chain of events that led to the crash. If it can happen to someone as Professional and capable as it did....then all of us are vulnerable.
My Condolences to the Next of Kin, the friends, and colleagues of the people lost in this sad tragedy.
