Probably question is out of topic, any reason for having Q-tips props?
My takeaway from this report has been summarized in the definition of “airmanship” on the last page of the report; it is quite impressive – “Airmanship is the consistent use of good judgment and well-developed skills to
accomplish flight objectives. This consistency is founded on a cornerstone of uncompromising flight discipline and is
developed through systematic skill acquisition and proficiency. A high state of situational awareness completes the
airmanship picture and is obtained through knowledge of one’s self, aircraft, environment, team and risk".
