Words mean nothing.
The words of the F/O certainly did mean nothing to the Garuda Captain. Neither did the words of the automated warnings. I am in agreement with what the F/O should have done as expressed by Centaurus and others. I am, however, also aware of the way in which many Asians think in relation to their position in the hierarchy of their company. It is all very well for us, who do not have the same cultural background, to be critical of the F/O in this instance. Many of the Garuda flight crew members are drawn from the Thai Airforce, where to question a "superior" would be considered as insubordination, and I am sure the F/O felt intimidated. That he did not take control of the situation was certainly a regrettable failure to assert himself. The fact is he did not, and all the posturing by others is futile. My question of those wanting the F/O's blood is "How many of you, as the F/O, have ever been placed in the situation which confronted the Garuda F/O?" None, I hope.
