From the Nov. 17 Sacramento Bee:
On Oct. 19th, while piloting the super-freighter The Grande Tetons down the Columbia River, Capt. Jackson collapsed from a heart attack and fell on the ship’s control mechanisms, causing the ship to lose control and careen across the river. The massive ship then plowed into the combination Sardine Canning & Dynamite Factory on the wharf resulting in a huge explosion and raining sardines all over the town. A radio announcer nearby was heard to cry out, ‘oh the humanity -‘.
