History for the day: 1947: the Grandcamp explodes

On 16 April 1947, America's worst harbor explosion occurred in Texas City, Texas, when the French ship Grandcamp, carrying ammonium nitrate fertilizer, caught fire and blew up, devastating the town. Another ship, the Highflyer, exploded the following day. The explosions and resulting fires killed more than five hundred people and left two hundred others missing.

Rico says this resulted in serious changes in shipping rules.
