Turbulence on a Continental Airlines flight from Ohio to New York battered around passengers and crew, injuring four.
Two people were taken to hospital.
Continental spokeswoman Julie King said Flight 2768 from Cleveland experienced severe turbulence as it approached Albany on Saturday afternoon.
She said the crew called for medical assistance to meet the plane when it landed at 1.50pm. She said two people were treated and released and two others, including a flight attendant, were taken to hospital for further evaluation.
Albany International Airport spokesman Doug Myers told the Albany Times-Union that a flight attendant and a passenger "struck their heads on the ceiling" and landed on the floor.
