At 18:00 CDT, a Bellanca 8KCAB Super Decathlon crashed near Atlanta, killing the pilot and seriously injuring the passenger. A witness said the pilot performed a loop, immelman, a couple of hammerhead stalls and a couple of rolls and returned to the airport. The witness said that the airplane then approached from the north in what I call a crop duster pass. At the end of the strip, he pulled the airplane up approximately 20-degrees to 25-degrees pitch and started a turn to the left. The aircraft banked left sharply and descended uncontrolled.
