Corrct. And a point that people keep overloooking. The Crew thought they were in the right place and had no reason to believe otherwise because nobody had told them that the computer had been changed the night before. And as I’ve siad previously, ‘whiteout’ was a phenomena that although known back in 1979, it wasn’t fully understood or appreciated in the commercial aviation sector. This accident caused changes in the understanding of whiteout and spacial anomalies.
