I’m sorry but this kind of thing by an airline is TOTALLY unacceptable. Don’t Northwest have SOPs? What the f@@@ were ATC doing? Surely there is radar in and around KRAP to monitor activity? Landing a Cessna at the wrong airfield I can understand – you don’t have a lot to help guide when compared to a modern digital commercial airliner with IRS/INS/GPS whatever Northwest have chosen to install. What plates were they reading? Surely a 7nm error in their mental picture should have triggered some alarm bells. My Company SOPs are very straight forward and insist on crosschecking all the time on an approach, instrument or visual. We do the crosschecking ALL the time even when going into our home base. I just find this kind of thing totally unacceptable in 2004. ATC should so also take the blame here. Amazing!
