An Indian Airlines aircraft experienced a catastrophic incident during takeoff, resulting in complete destruction and fire. The aircraft became aerodynamically unstable due to the failure of leading edge devices immediately after rotation during take-off. The aircraft was flared for a belly landing with undercarriage retracted, resulting in a significant slide and impact with a boundary fence, drain, and terrain. The incident involved fatalities due to the impact and resulted in a fire.An Indian Airlines aircraft experienced a catastrophic incident during takeoff, resulting in complete destruction and fire.
