HOUSTON -

At least 12 people were injured Wednesday during turbulence on a flight from Tampa to Houston.

United Airlines officials said Flight 1727 experienced the heavy turbulence over Lake Charles, La.

Sources told KPRC Local 2 that the plane suddenly dropped about 6,000 feet, throwing food, drinks and people around the cabin. Photographs taken inside the plane show coffee and food splatters on the cabin's ceiling.

The plane landed at 7:30 a.m. at Bush Intercontinental Airport. Officials said 152 people were on board, including 6 crew members and 146 passengers.

Eight people were transported to area hospitals, according to an airport spokeswoman. Their conditions were not released.

At least two crewmembers were among the injured and wore neck-braces as they were wheeled out of the airport on stretchers.

Crewmember Allen Dutton was one of the ones taken to a hospital.

"I was taking a lady a cup of coffee," he said. "I had come back in the galley and was trying to put the other stuff away, then all of a sudden ...."

The injuries were described as minor. Most patients have been treated and released.

The plane was a Boeing 737, officials said.
