can anyone actually think of a time someone other than the regular crew HAD to land the plane? (let's put helios aside as no one landed that plane)
Yep, that's the point.
Back to the topic. Emergency scenarios, especially with CC, should be cause related, not academic.
AFAIK, there was never ever a case of both pilots incapacitated.
Yeah 9/11, okay, open the cockpit door for their friends
