asked Kristen Brengel of the National Parks Conservation Association, noting that visitors on the ground far outnumber those overhead. Congress passed another round of legislation in 2000 with a goal of setting rules in other national parks. Historically, some of the nation's busiest spots for tour operators are Hawaii Volcanoes National Park, which is home to one of the world’s most active volcanoes, and Haleakala National Park. But Brengel of the National Parks Conservation Association said the resistance doesn't have much traction. An amendment to the FAA reauthorization bill that would have required the agency to factor in the economics of commercial air tours over national parks failed in July, she said.
