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

Delta Air Lines says a flight from Salt Lake City to Amsterdam was hit by serious turbulence, sending 25 people to hospitals and forcing the flight to divert to Minneapolis-St.
