Task: Question Answering
Input (English): Passage: U.S. Army Air Forces fighter pilot Johnny Martin is diagnosed with nerve exhaustion at his discharge medical and is prevented from flying for a year. Instead he goes home with one of the other pilots, Miles Cary, to his hometown in Iowa. While Miles returns to his family and his job at the bank, Johnny has a hard time adapting to the tedious ordinary life in the small town and starts working as a bus driver. One day he quits his job. 
Joe Patillo, his other pilot buddy from the Army, is planning to start flying again, using a surplus Douglas C-47 transport aircraft. Johnny and Miles both agree to join Joe in California where Joe lives, and get their first job, to fly to New York.
Since Johnny is forbidden to fly, Miles and Joe fly the C-47 to New York. Miles's wife Sally is anxious about him flying again and asks why Johnny is not flying. Ashamed over his inability to fly. Johnny lies, telling Sally that he needs to work with the administration and marketing of the company.
Joe and Miles return with a passenger in the aircraft, Anne Cummings. Johnny is upset since he was not informed, and does not calm down knowing Anne paid for the trip. He is further upset when he finds out that Anne is hired as the new company mechanic.
Johnny keeps trying to get business for the company and works hard to get a contract with oil tycoon J.P. Hartley. He fails because Hartley considers their operation too small to carry out the work. Instead they continue flying for other companies.
After a while Anne demands they use the earnings on repairing the aircraft. Since the men do not follow her advice she takes matters in her own hands and talks to the owner of a garage, Harry, about the repairs and the aircraft is transported there. 
Question: What is the last name of the person that quits work as a bus driver?
Output (English): Martin.
