At about 0755 Eastern time, the airplane collided with two telephone poles and wires during a go-around. Visual conditions prevailed. The airplane was substantially damaged; the Commercial pilot and pilot-rated passenger were seriously injured. According to witnesses, the airplane was observed near the middle of the runway approximately 20 feet above ground with its landing gear retracted. One witness-who recently witnessed a gear-up landing-reported hearing a scraping noise similar to that incident. The airplane climbed to an estimated altitude of 100 feet, then disappeared from view.
