Looks like an ordinary ship at an ordinary dock on an ordinary day. However, the moment captured is April 16, 1947 and the ship is called SS Grandcamp. A fire has broke out and the men on the dock are members of the Texas City Volunteer Fire Department, attempting to extinguish it. A few minutes after this photo was taken, it’s going to detonate in one of the largest non-nuclear explosions in human history. 468 people had died, more than 5,000 were injured.
