The Ask in Soar is his motorcycle accident, the moment he becomes a quadriplegic with only 6% of his body function at the age of 19. This is where his Conflict is introduced, Man vs. Self. It literally asks something of Dave, will he have the strength to rebuild—to gain his independence back? Or will he always have a fraction of the independence and freedom that he once had?
A Hurdle for Dave then was other people's limiting beliefs. At first, Dave had trouble finding an instructor who was willing to teach him to fly. They didn't believe that a man who was quadriplegic would be able to fly a plane.
