An air traffic controller was hailed a hero after he sacrificed his own life to ensure a passenger plane carrying dozens of people safely took off during an earthquake in Indonesia.
As his colleagues fled the Mutiara SIS Al-Jufrie airport, near Palu, in Central Sulawesi, 21-year-old Anthonius Gunawan Agung held his ground as the 7.5-magnitude earthquake struck.
He had just cleared Batik Air flight 6231 for takeoff as the ground started to shake, but instead of running for safety he waited until the plane was airborne before finally leaving the air traffic control tower.
Trapped as he attempted to flee, Mr Agung was forced to jump from the fourth storey of the tower as the tremors grew stronger.
He suffered a broken leg and internal injuries and although he was taken to hospital, he died while waiting for a helicopter to take him to a different hospital for specialist care.
Air Navigation Indonesia spokesman Yohannes Sirait said Mr Agung’ decision to stay behind cost him his life, but he may have saved everyone on board the plane as the city was later ravaged by a tsunami.
Mr Agung, who would have turned 22 on 24 October, had his rank increased by two levels in recognition of his “extraordinary dedication”.
Soldiers carried his body as it was transported for burial."
Still not entirely plausible as an explanation, the poor chap may have been simply the last one out of the tower as the earthquake hit.
