2 hadn't - yet. but can you guarantee that another one won't ? Highly unlikely, but what if ??
That's why I asked the question.
So unless he thinks they had two failures, then Hautemunde seems to be saying if a second engine
were to fail in a high terrain, they'd face a driftdown scenario. Fair enough. And just like the twin does on every flight, for the case of a
single engine failure.
