The crew knew there was a blob in front of them yet did not take timely action to avoid it, so yes, in my world, that falls on the captain’s broad shoulders. Same responsibility as if they were to deviate from an SOP because of an on-the-spot assessment - like Sully did.
Anyway, lots of blame to go around, especially management. Crew selection, command assessment, SOP’s appropriate for avionics and location....looking forward to the report. Though I think ppruner’s work will be cut out for them to assign the correct weigh of each finding to the tragedy.
