A plane made an emergency landing at Minneapolis-St. Paul International Airport on Wednesday after dozens of people were injured by "significant" in-flight turbulence, according to the airline. The airport says Delta Air Lines Flight 56 en route from Salt Lake City to Amsterdam diverted to MSP, landing safely around 7:45 p.m.

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.
