At about 16:40 eastern time, a Cessna T206H lost engine power and was ditched in Lake Lanier. The pilot and passenger were not injured. The pilot said he was being vectored by ATC while on an IFR flight plan when he heard a bang and felt a vibration. He declared an emergency and got vectors to the nearest airport, but couldnt reach it, so he elected to ditch the airplane in the lake. The airplane flipped inverted but both occupants made it out of the passenger window.
