Air Dog Bell 206 doing training had an engine failure of some sort....Training Captain made a routine engine off landing to the water. Only difference was the engine was not working whereas it would have been during the practice.
A Bell 407 had an engine problem....found itself being transported by workboat.....some suggestion the tailboom got bent somewhere after takeoff and when it arrived at the dock....maybe someone in the GOM can add more to this.
Except for the circumstances....could have been two more ditchings to add to the list.
