Concerns over the young age and apparent inexperience of the first officer on KQ Flight 507 has always been part of the discussion of the 2007 crash in Douala, Cameroon. But if the report released on Wednesday is anything to go on, we must add to that his pairing with a pilot who allegedly had "performance deficiencies" going back five years before the crash. The interaction between the two seems to have played as important a role as their training and experience.
The report says the pilot and his first officer both made critical errors.
