Some great and prescient posts above. Particularly fdr and his assessment of nationality versus flying skill. Great pilots are made either naturally or with training or both regardless of origin. If you think the Koreans can’t fly have a look at their aerobatic team that currently knocks spots over all others. Nobody outwith the crew knows what really happened with this accident but in time honoured fashion people are prepared to instantly criticise from their armchairs before official investigation.
