Officials say a United Airlines jet carrying 121 people skidded off a runway when it landed at the Jackson Hole, Wyo., airport. There were no major injuries.
An airport official says passengers used emergency slides to get off the plane after Monday night's mishap. One passenger sprained a wrist while exiting the jet.
The plane, arriving from Denver, was carrying 115 passengers and a crew of six.
The National Transportation Safety Board plans to investigate the incident.
