In the early hours of July 6, a train of 72 tankers carrying crude oil slips its breaks and rolls downhill, jumping the tracks and exploding in the small town of Lac-Mégantic, eastern Quebec. The flames and fireballs could be seen for miles. Forty-seven people died in the explosions and fires that followed. Many of them were in a nearby café.
