A Boeing 747 struck some bad turbulence Saturday on a flight from Paris, injuring one passenger critically and causing minor cuts and bruises to about 20 others.

Tower Air Flight 037 landed about 2:45 p.m. at John F. Kennedy International Airport about a half-hour after hitting the turbulence over the Atlantic Ocean.Injured passengers were taken to Jamaica Hospital Medical Center, said Alan Hicks, a spokesman for the Port Authority of New York and New Jersey.

Hospital officials would not provide details of the critically injured passenger.

Tower Air officials did not immediately return calls seeking comment.
