I wasn't talking about the sterile cockpit part when I said goofed up.Its not "goofed up" at all for his company procedures. See the above post.
They just thought they were somewhere they weren't. Now whether or not complete silence would have prevented that is impossible to know, but I seriously doubt any of their conversation contributed to making a wrong turn.
That runway layout was an accident waiting to happen. Even when you line up on 22 instead of 26 it looks unusually short because it has a hill that peaks in the middle.
I think some blame should be placed on the airport for not baracading 26 off since I do believe it was closed at the time of the accident.
