Plane with 140 people aboard skids off runway into Florida river

A jetliner slid off a runway and into a river in Florida's Jacksonville area Friday night, officials said.

The plane, a Boeing 737, was arriving from Cuba into Naval Air Station Jacksonville about 9:40 p.m. and crashed into the St. Johns River at the end of the runway, the station said.

The plane hit rough weather and slid off the runway, an aviation source told NBC News on Friday.

Mayor Lenny Curry said that all lives had been accounted for, NBC affiliate WTLV reported.

It was carrying 136 passengers and seven crew, according to the naval station.Initial reports indicated that 150 people were on board.

Tom Francis of the Jacksonville Fire Rescue Department said Friday night that 21 adults had been transported to area hospitals and that all were in good condition.

The plane was in shallow water and not submerged, according to the Associated Press.

The contract flight was headed from Naval Station Guantanamo Bay to NAS Jacksonville.

Curry said rescue crews were trying to control jet fuel that spilled or leaked into the river.

Navy security and emergency response teams were at the scene and monitoring the situation, the Naval Station said.
