Airplanes and helicopters continue to erode natural quiet in Grand Canyon — despite the passage of key legislation in 1987.
Since its founding in 1985, Grand Canyon Trust has worked to protect the solitude and stunning quiet in Grand Canyon National Park. Nevertheless, over time, a growing number of air tours has eroded the Park’s serenity and replaced it with the sounds of throbbing helicopter rotors and airplane engines.
The Trust was instrumental in securing passage of the 1987 National Parks Overflights Act, which sought to regulate the expanding air tour industry.
After more than two decades of interim flight rules, the National Park Service recently issued its proposed management plan to implement final rules.
