Accident Sequence
A witness flying in the traffic pattern observed the jet crossing the shoreline heading westbound at approximately 50 to 75 feet above the ground. The airplane then made an abrupt turn from west to north, descended into trees, and a fireball was seen. Ground witnesses reported the airplane making a hard descending right turn, striking a power pole, and then impacting the ground.
