Alternative scenario:
- Student pilot, not doing well in flight school, gets reprimanded by the instructor
- The student, mad at the instructor, starts flying aggressively, "showboating" his "skills"
- The instructor, having enough of the situation, decides to take control and says "My Plane"
- Student refuses to cede control, struggle ensues, plane crashes
No terrorism, no suicide intent... just heated argument between student and instructor.
