... and just to make you happier, the pilots are claiming an autothrottle failure ...
Now the CIAIAC is gonna have to go through the trouble of analyzing the performance from the DFR and "prove" that the autothrottle was fine
The investigation is gonna take a while.
I guess some pilots just can never make a mistake or a bad judgement call, like we all do in our daily jobs every once in a while.
The usual disclaimer: nobody flat-out rules a failure of any kind. It's just that it looks a lot like the cause could be a different one. Each person is entitled to its opinion and any opinion could ultimately be wrong.
