The captain has always done well before this accident will always remain. If anything is found wanting then it's only human but will help prevent recurrence. I remember NTSB Chairman in 2000 James Hall saying"I am a history major. I believe past is prologue. But all accidents are not acts of God. We take what we learn so it doesn't happen again. But that ain't gonna happen if nobody says anything". So investigation will have look into everything.
