WASHINGTON — The National Park Service today recommended that the Federal Aviation Administration ban low-level flights over 44% of Grand Canyon National Park in Arizona.
The service also called on the FAA to consider moving high-altitude commercial jet routes away from the canyon. The recommendations by the service were required earlier this year by Congress. There are an estimated 50,000 flights a year over the canyon, as many as 90% of them low-level trips by tour operators that disturb backpackers' quiet. In June, 1986, the collision of two planes over the canyon killed 25 people.
