At about 12:05 EST, a Beechcraft 90 landed short of the runway at St. George Airport while on a parachute jumping flight. The pilot was not injured. The pilot said he took off at about 11:50 and was at 12,500 feet when the aircraft started to lose power and descend. He instructed the parachutists to jump and turned toward the airport, but landed about 500 yards short of the runway. All of the parachutists exited the aircraft safely.
