Ten people were hospitalized Saturday after landing in Philadelphia on an American Airlines flight from Athens, Greece, that had encountered heavy turbulence.

The three passengers and seven crew members were taken to a hospital for evaluation after Flight 759 landed at Philadelphia International Airport, American Airlines said in a release.

The turbulence was encountered shortly before the plane's 3:12 p.m. arrival at the airport, according to the airline.

American Airlines spokeswoman Sunny Rodriguez had no immediate details Saturday evening about injuries sustained by passengers or crew members, or whether those injured remained hospitalized.

Jessica Huseman, a reporter with the news website ProPublica who was on the flight, said in a tweet that a flight attendant had dislocated his shoulder during the incident.

"No warning at all. Plane lurched thru the air. Honestly, terrifying," she wrote in a separate tweet. "Some passengers are injured as well."

Huseman also posted photos of the airplane cabin's ceiling splashed with coffee that had just been distributed to passengers when the turbulence occurred.

"We all used our fleece blankets to mop the ceiling of the plane down after drinks went flying," Huseman wrote.
