The court also instructed the FAA to include noise from commercial jets and other aircraft flying over the canyon in their new calculations. The net effect is sure to reduce the number of sightseeing flights audible to park visitors.
Geoff Barnard, president of the Grand Canyon Trust, said, "It is going to balance overflights with providing a good experience for everyone who is visiting."
Earthjustice attorney Robert Wiygul said, "This decision will go a long ways toward stopping the assault of aircraft noise on the average visitor to the Grand Canyon National Park. The Grand Canyon is probably the single best known geographical feature of the United States of America and we should not treat it like a subway station."
Wiygul litigated the case on behalf of the Grand Canyon Trust, the Sierra Club, The Wilderness Society, National Parks and Conservation Association, and Friends of the Grand Canyon. Alex Dreier of the Washington DC firm of Hogan and Hartson served as co counsel.
