I knew of the story and found it interesting when I found it on the Internet.
If you could find it, it told how they fell over sick one by one, then they asked for a pilot and this man was the only one who had any idea what went on in the cockpit.
The story that I read was the man's history and story, with
of course the part about landing the plane.
But he did land it and live to tell about it.
