RAPID CITY, S.D. - A Delta Airlines flight from Minneapolis to Rapid City landed by mistake at an Air Force base instead of the airport.

The flight landed Thursday night at Ellsworth Air Force Base instead of the Rapid City Regional Airport.

Military personnel walked through the cabin while the airplane was at the base. Passengers were ordered keep their window shades down. The flight eventually took off from the base and arrived at the airport at 11:31 p.m.

Delta Airlines in a statement says the crew has been taken off duty while the National Transportation Safety Board investigates the incident. The airline says it is also conducting an internal investigation.
