In 1921, more than 80% of the northern third of the vast plant at Oppau, three miles northwest of Ludwigshafen, had gone up in one terrible roar that took 565 lives. Just five years-minus one day-before this week's explosion, a similar blast had taken 73 lives. During the war 120 Allied bombing raids had smashed more than half the plant.
