Why A Triangle?

Notice nobody agrees on the Triangle's exact corners. Different writers draw it differently, stretching or shrinking the borders to swallow whichever wreck they want to include.

That is the trick. Draw a big enough box over one of the busiest shipping and flight corridors on Earth, where over 100,000 ships pass each year, and of course some are lost. Heavy traffic guarantees occasional accidents. Pull every accident into one shape, ignore the safe crossings, and a normal ocean starts to look cursed.
