Answer: One great conflict in "Dragonwings" by Laurence Yep is when Black Dog, Uncle Bright Star's evil son, robs and threatens them. Windrider gives him the money; they were so close to achieving their goals and, once again, they have lost everything.
After this latest setback, the Company and the Whitlaws support them, giving them financial aid and coming to watch them fly their plane.
Another conflict is when on one flight, the frame of the plane snaps, and Windrider breaks a leg and ribs. Now, he realizes that family is more important than killing yourself to reach objectives.
