“When the same happened here, the pilots turned the switch off. “
You obviously do not know the whole story.
BS, got it from an active pilot after the two crashes. The foreign pilots were undertrained by any stretch of the imagination. I am a Safety School grad and it is obvious when two different pilot groups have different outcomes from the same 'emergency', it is no longer a 'system fault' causing the accidents. It is training and experience. Your EXPERIENCE may differ, but it is no longer fact based.
