My feelings have already been duly noted on the survey. But I have good mentors who aren't afraid to use the parking brake.

To the poor student that may get the joy of defending their study, a simple question was left out which may affect results: "Airline pilots are losing their authority." If the person taking the survey agrees with this statement, then the results of the following questions may show the reasons. If the person does not agree with that statement, then all of the following answers could be due to the perception of no loss of authority, versus a particular cause. While it may not invalidate the study, it is certainly worth exploring in the results, or thinking about it before arriving at the thesis grilling.
