A single-engine airplane has crashed in the northern part of Yellowstone National Park, seriously injuring the 54-year-old pilot.
Federal Aviation Administration spokesman Allen Kenitzer says the Aero Commander airplane went down at 8:30 a.m. Monday, less than two miles east of Gardiner.
Park spokesman Al Nash says the pilot was the only person on board. He was flown to Bozeman Deaconess Hospital for treatment. The man's name hasn't been released.
According to the FAA registry, the airplane was registered to a company in Pray, Montana.
Kenitzer says the National Transportation Safety Board is investigating the crash.
