Pilot Error.
He could have landed at Burbank but declined.
Descended slowly in final moments - then went forward at 150 mph.
The pilot is ultimately responsible for the safety of the aircraft and his passengers.
Barring mechanical failure - he f€cked up and killed eight other people.
No one seems to be talking about the 2500 ft. ceiling he seemed to be restricted to.
Probably to prevent a mid air collision with fixed wing aircraft.
Whoever was allowing helicopter flights in dense fog with a low ceiling should be held accountable.
That - should have never happened.
