Twenty-five people aboard a Delta Air Lines flight were hospitalized after the flight encountered "significant" turbulence Wednesday, the airline said.

Flight DL56 from Salt Lake City to Amsterdam "encountered significant turbulence" and landed at Minneapolis–Saint Paul International Airport, the airline said.

Some passengers were terrified, convinced the plane was going down. One seasoned traveler said it was the roughest flight he’d ever taken. A woman on board felt like she was experiencing an earthquake.
