On the morning of December 6th, 1917, Pilot Francis Mackey was guiding the French ship Mont Blanc into the Bedford Basin when, at the narrowest point of the harbour, the Norwegian ship Imo collided with it. The Mont Blanc, laden down with high explosives, caught fire and, about 20 minutes later, exploded. \nThe blast, which was the greatest man-made explosion until the invention of the first atomic bombs, levelled the Richmond district of Halifax, parts of Dartmouth, and wiped out the Mi\u2019kmaq community of Turtle Grove. \nOn today\u2019s episode, we talk with retired teacher and author Janet Maybee. Her book Aftershock: The Halifax Explosion and the Persecution of Pilot Francis Mackey attempts to clear Mackey\u2019s name and restore honour to the Mackey family.
