The Bermuda Triangle: what the records say, and how the legend grew.

Where the Triangle is (and why it has no official edges); the real story of Flight 19 and of USS Cyclops; the storms, currents and compasses that NOAA and the Navy point to; and how a 1950 news story became a world-famous mystery. Every fact is linked to its source, and there is a quiz at the end.

The short version

NOAA says there is no evidence that mysterious disappearances happen more often in the Bermuda Triangle than in any other large, busy area of ocean. NOAA

The Bermuda Triangle is a stretch of the western North Atlantic where ships, planes and people are alleged to have vanished mysteriously. NOAA

Most Atlantic tropical storms and hurricanes pass through the Bermuda Triangle, and before better weather forecasting they claimed many ships. NOAA

Flight 19 was the most significant event behind the Bermuda Triangle myth. NHHC H-Gram

Larry Kusche found that roughly half of the so-called unsolved mysteries happened far from the Triangle, some thousands of miles away. Skeptical Inquirer

Where the sources disagree, we say so. Where people died, we stick to the records.
