The difference between the NWA pilots being terminated and the Delta pilots that landed on the wrong runway in ATL, is the way the media handled the story and more importantly, the way the company handled the media. The FAA assisted in the flow of information in both incidents. NWA, high flow, DAL, low flow.
Both these incidents happened within a few weeks. It is far more dangerous to land on the wrong runway, than overflying a destination in my humble opinion.
