So you can probably see where this is heading.
The Torrey Canyon's problems started with Capt. Pastrengo Rugiati, who, like most Italian oiler tanker captains, had a few bad habits. One was that he liked shortcuts, presumably so he could get home to perpetuate some Italian stereotypes, like eating spaghetti and extorting bribes. Another was that he kept forgetting whether his ship was set to "automatic" or "manual," which is semi-important when you need to make some tricky maneuvers in a hugeass supertanker. And finally, he appointed the ship's cook as his helmsman.
"The captain is on the starboard side, and I'm drunk on the port."
Shockingly, all of this coagulated into a blitzkrieg of stupid that landed the Torrey Canyon smack dab in the middle of the Seven Stones, a ridiculously famous reef off the coast of Cornwall.
And ... crash.
