Episode 16: Ship Happens! - The Largest Man-Made Explosion Before the Atomic Bomb

Two ships. One harbor. Three thousand tons of explosives. What could go wrong? In 1917, a French munitions ship and a Norwegian relief vessel played the world's slowest game of chicken in Halifax Harbor. They collided at one mile per hour. Twenty minutes later, the largest man-made explosion before Hiroshima vaporized an entire neighborhood. The anchor landed two miles away. Hundreds of people watching from their windows were blinded by flying glass. And then a blizzard hit. But hey, Boston sent help, and now they get a free Christmas tree every year. So... happy ending?
