As an air taxi pilot and an avid user of the south district of Denali national park, I read the article with attention.  Before I flew planes daily over Denali national park, I climbed and worked as a guide on Denali for nearly a decade. I am proud (and humbled) to say that I have journeyed on foot over the majority Denali park on foot.  My only access: aircraft.  The access for the soundscape study: aircraft. 
          When a plane flew over, it was a friend and not a foe. The south district of Denali national park itself is a staggering 4.3 million acres. The only access: aircraft. Roughly 20 percent of the state of Alaska is accessible by car. The airplane has been an integral and irreplaceable part of our heritage since Alaska started being, well, Alaska. 

The heavy opionion and title of the article are inappropriate. I would not tell my four year old daughter to ' shut up,' and neither would I suggest so for the rest of us who love and use the south district.
