What a horse's ass.  I did not know that reading an encyclopedia article required due diligence.  Yea, my bad.  I should have know to look up FAR 91.167.  Geez, silly me for not knowing that clearly obvious fact!  How stupid of me!  I am sure that 99.999999% of the other Wikipedia readers (a) all did their due diligence before reading this article ... and (b) went and read FAR 91.167.  You are so full of yourself.  I am not impressed with your level of genius as you are clearly impressed with yourself, your ability to conduct due diligence, and your vast knowledge of the FAR reports.  What an ass, seriously.    )
