GEORGE TOWN, Cayman Islands -- An American Airlines Boeing 757 carrying nearly 200 people made an emergency landing in Grand Cayman Sunday after stopping in Miami, and two passengers suffered minor injuries, officials said. "The pilot declared an emergency after a problem with the de-icing equipment,'' airlines spokesman John Hotard said. ``As the plane was clearing 28,000 feet on its descent into Grand Cayman, the aircraft experienced moderate turbulence.''
