Over two dozen passengers were injured after a Delta flight from Salt Lake City struck severe turbulence, forcing it to make an unplanned landing in Minneapolis.

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.

Serious injuries from in-flight turbulence are rare, but scientists say they may be becoming more common as climate change alters the jet stream.
