"Not to mention, they were also distracted with non-essential communication between each other all the way from their departure airport on a pretty short flight. Reference the CVR... the Captain didn't even adjust his seat for the approach until he was on a last vector for the ILS. They were still chatting in bad weather at night on an ILS 2 minutes before the crash!"
