Scary Indeed
Its really scary that the 2 pilots didnt know their aircarft Systems VERY WELL.
I would like to get a copy of the CVR to see what kind of SOPS were or were not followed, which would have prevented this from happening, all be it at very very high workload of the first approach.
Whats more appalling, is the safety culture demonstrated by the handful of personnel within the organisation to sweep it under the table.
When one does not acknowledge a problem and or a mistake there can be no remedy nor learning to prevent such incidents happening again which is the most sacriest indeed
