USA Today | In an attempt to restore natural peace and quiet to the Grand Canyon, the National Park Service has proposed limits on "flight-seeing" and other aircraft over the canyon.
The proposal raises height limits for aircraft flying over the area, suggests no-fly zones and calls for phasing in quieter aircraft.
Air tours currently carry about 400,000 passengers annually over the canyon. And while "they play an important role in visitor enjoyment … without more thoughtful management, air-tour flights can interfere with the enjoyment of visitors on the ground," the park service said in a statement.
