On July 11, 2011, two high-speed 'bullet' trains collided in Wenzhou, China, killing 40 people and injuring over 190. It was the second-worst high-speed train wreck in history.
As a disaster documentary buff, I've occasionally dashed over to YouTube to see if some company like the people who produce the 'Seconds From Disaster' or 'Mayday' series have done a special on it.
But I've left disappointed. No one's ever produced a comprehensive documentary covering the entire sad event.
Until now.
