#NEPAL: This is incredible. 1,643 children survived because one headmaster acted fast when disaster was already on the way. He received a warning that a village upstream had been swept away by the river. He immediately rang the school bell and moved the children and teachers to higher ground. School buses were on the way to school, He called the bus drivers and told them: "Don't come here. Go back." One school bus was already on its way. The headmaster saw it approaching the bridge and told the driver to turn back. The bus reached safety just before the bridge collapsed. Then the flood hit the school. The entire three-storey school was washed away. It completely vanished. Not even a trace was left behind. But all 1,643 children survived. 47 year old Rajendra Dadabi a teacher who became a hero when it mattered most. One man's quick thinking saved 1,643 lives.
