In a written statement, the pilot reported that he performed a normal landing approach to runway 12 at Laramie Regional Airport. As the airplane entered the traffic pattern, the pilot indicated he was a little high, but at pattern altitude as he came abeam the runway approach end. Upon turning to final approach, he added the final flaps. He was on the glide path at the normal airspeed and crossed over the runway numbers at 77 knots. The airplane floated as he began the flare, and he noticed that the ground speed was very fast. The pilot continued the flare "as normal" when the stall warning horn sounded. He looked down and saw that the airplane was about 10 to 15 feet above the runway. He applied full power and right rudder to perform a go-around, but the airplane did not climb as expected and drifted to the left. He also added right aileron control inputs to maintain airplane control, but there were no positive results from the manipulation of the aileron. The airplane continued to descend, and the left wing touched the ground and hit a taxiway light. The airplane exited the runway and impacted the ground before coming to rest upright.
