At about 20:00 eastern time, a Cessna 152 nose-dived into the ground during low-level maneuvering near La Grange, killing the student pilot. Witnesses said the pilot called his home by cell phone while airborne, saying hed soon be flying overhead. He circled his house at 100 to 300 feet, wagging the wings. After about five minutes, the airplane flew toward a prison complex and suddenly nose-dived into the ground. No pre-crash anomalies were found. The flight instructor said he had approved the students solo flight to practice coordination exercises and advised the student pilot not to do any low flying or any other inappropriate flying. The instructor said the student assured me he was past that sort of thing.
