A Delta flight had to be diverted to Minneapolis-St. Paul International Airport on Wednesday after it encountered “significant turbulence,” leaving 25 people injured, seven of whom were crew members. Delta on Thursday said the 25 in the hospital have since been released.

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.
