....responsibility for this accident lays fully with the pilot in command...
Within the current legislation and as it is laid down, I concur. And that will be a very inconvenient truth for a great many involved parties, so don't expect them to necessarily take this line (hence various interested parties effecting outrage over the criticism of the pilot, by the aviation community.)
All that said, we all know where the blame for the current opaque legislation and grossly ineffectual enforcement lies. And because of that the pilot was, IMO, both responsible and a victim at the same time.
