Runway Zero- Eight

Here is an excerpt from the book that says it all:

"We are in distress... Atleast five passengers are sick. Both the pilots are unconscious, I repeat, both the pilots are unconscious and in serious condition. My name is Spencer, George Spencer. I am a passenger of this airplane. Correction: I was a passenger. I am now the pilot."

What happened? Who was the new pilot? Would anyone reach the ground safely, or for that matter even alive? This awesome tale by Arthur Hailey will leave you clutching your seats and gripped on to the tale.
