Interesting that Eva were given a right turn onto 180 which they completely ignored - hence they ended up going into the mountains.
In the initial tx from the controller we do not hear whether she said "left" or "right" heading 180. We only hear EVA acknowledge "left" heading 180. The question remains whether she inadvertantly said "left" or if she did mean left as in all the way around. My own experience is that controllers generally, for clarity, add "the long way around" in their tx when giving such turn instructions. 98% of the time LAX traffic departs on westerlies and indeed turn "left" heading 180. There is an outside chance that in a moment of distraction (a great deal goes on simultaneously on a controller position) she did say "left" by habit. This may have confused the EVA. However, the crew should have immediately sought confirmation.
