A small corporate jet landing in Atlantic City (search) ran off the runway when its brakes failed, careening into a bay. None of the four people on board — rescued by a boater and some residents — were seriously injured.

The Charlie Cessna Citation C-25A (search) crashed about 4:30 p.m. Sunday at Bader Field Airport, authorities said.

The pilot, co-pilot and two passengers — all residents of Denmark in Atlantic City for a convention — were returning from a trip to Burlington, Vt. They were taken to a hospital where they were treated and released Sunday night.

An unidentified boater fishing in the area pulled the co-pilot and the two passengers from the jet. Some area residents who saw the crash used a small boat to reach the pilot.

One of the residents, Joe Clark, told the Courier-Post of Cherry Hill that the pilot was "calm but concerned with the plane."

Clark said he thought about using the boat to tow the jet closer to the docks but he abandoned that idea when one of the aircraft's engines suddenly revved up, causing flames and smoke to shoot out.

"I thought it was going to blow up," Clark said.

The 10-passenger jet, owned by Weibel Scientific Inc. of Denmark, was expected to be towed away sometime Monday.

A company spokesman declined comment on the crash, which is being investigated by the Federal Aviation Administration, the National Transportation Safety Board and state police.
