Delta reported after the incident that 25 passengers were taken to various hospitals for evaluation and medical treatment.

Serious turbulence on a Delta Airlines flight headed to Europe sent 25 people to hospitals and forced the plane into an emergency landing in Minneapolis, the airline said. Some aboard the flight from Salt Lake City to Amsterdam weren’t wearing seat belts and were thrown about the cabin, one passenger said.

Delta Air Lines Flight 56 landed safely at the Minneapolis-St. Paul International Airport shortly before 8 p.m. local time Wednesday, the airline said. The flight was operating on an Airbus A33-900 with 275 passengers and 13 crew members on board.
