Twenty-five people were hospitalized Wednesday after a Delta Air Lines flight experienced extreme turbulence, forcing the plane to make an emergency landing in Minnesota. According to some of the plane’s passengers, the turbulence was so severe that people were tossed into the air.

Delta flight DL56 was flying from Salt Lake City to Amsterdam when it “encountered significant turbulence while enroute,” the airline said in a statement.

Passengers said anyone not wearing a seat belt at the time of the turbulence was violently thrown into the air. Leeann Clement-Nash detailed what she saw to ABC News.

“They hit the ceiling, and then they fell to the ground,” she said. “And the carts also hit the ceiling and fell to the ground, and people were injured. And it was, it happened several times, so it was really scary.”

Fellow passenger William Webster told CNN that he was wearing a seat belt at the time, but that the turbulence still lifted him out of his seat “for like 30 seconds.”
