I think you're missing the point. In hindsight it's easy to say "this is what you could/should have done", and some are knowledgeable or lucky enough to either find the solution themselves, or have someone tell them before it's too late.

In two instances this wasn't the case. The pilots weren't able to regain control of the aircraft. And that lack of control, with the full knowledge of impending doom, must be a terrifying feeling.
