Impact verdict
Medium impact. The incident involves a hull loss or significant damage to an Airbus A321, passenger injury claims, and potential liability exposure for the airline and airport authority. However, the aircraft was on the ground at takeoff speed rather than airborne, limiting catastrophic loss potential, and passenger injuries appear minor.
