Sorry folks, placing everything else to one side, I still can not understand, just why an immediate evacuation on the ` relatively safer` side was not immediately carried out. I would fully accept, that by evacuating in this particular case, you might possibly fry, but by remaining on the aircraft in such a situation, had it suddenly got worse as they so often can, you are almost bound to fry. No winners here & SQ as a major world airline, should front up themselves, just to reassure their customers. Forget the face saving culture that exists in their part of the world, be up front & we might be able to understand, just why things played out here as they did.
