The Bermuda Triangle: Can Incident Counts Alone Establish Greater Danger?
A sea area famous for stories of vanished ships and aircraft. Separate individual records from claims about a whole region, then compare incident counts with total journeys.
First, what is the Bermuda Triangle story?
The Bermuda Triangle is a name associated with stories of unexplained losses of ships and aircraft in the western North Atlantic. NOAA does not describe an officially bounded geographic area.
A well-known documented loss is Flight 19, a U.S. Navy training flight that failed to return on December 5, 1945. The National Archives preserves contemporary investigations and correspondence. A documented loss and proof of a particular supernatural cause are different things.
This reading does not declare every case solved. It asks a separate question: did incidents occur more frequently than elsewhere? Invented numbers show why a list of incidents needs a comparison with the journeys made during the same period.
If one area has 30 recorded incidents and another has 20, is the more dangerous area already established?
Flight 19 is a documented loss
On December 5, 1945, five Avenger aircraft on a training mission from Florida did not return. They carried 14 Navy and Marine personnel.
The National Archives guide introduces contemporary investigations, communications and correspondence. We retain the documented loss without declaring every detail settled or assigning the same cause to other disappearances.
A familiar name need not have official boundaries
NOAA explains that there is no official boundary map or recognized official geographic name. A triangle associated with a popular name is not automatically a defined research area.
Changing which incidents enter a list can change its length. Comparing whole regions requires a defined area and period rather than an impression created by a name. We draw no triangle resembling an official boundary map here.
The same incident counts can represent different shares
Incident journeys stay at A 30 and B 20
When totals match
A and B: 1,000 total journeys each
A30 / 1,000 = 3%
B20 / 1,000 = 2%
Shares: A 3% > B 2%
When totals differ
A total 3,000 / B total 1,000
A30 / 3,000 = 1%
B20 / 1,000 = 2%
Shares: A 1% < B 2%
An individual cause and greater frequency are separate questions
NOAA’s institutional explanation finds no evidence of more frequent mysterious disappearances than in other large, busy sea areas. This reading has not independently collected and analysed all navigation records.
To examine a comparison, place the incident count beside total journeys. Count one journey consistently over the same period, counting a journey with an incident only once. We can then distinguish how many from what share of the whole.
Activity 1: change both journey totals together
Invented Area A has 30 journeys with recorded incidents; B has 20. With 1,000 total journeys in each, the shares are 30/1,000 = 3% and 20/1,000 = 2%.
Changing both totals to 2,000 makes A’s share 1.5% and B’s 1%. Counts stay at 30 and 20, and A still has the higher share. The same counts now occupy smaller shares of the totals. This compares two possible denominators; it is not an experiment showing that adding traffic prevents accidents.
- Flight 19 fails to return
Records document the loss of five training aircraft with 14 personnel aboard.
- NOAA publishes its explanation
The current page identifies when its text was first posted. A later explanation’s date is distinct from an incident date.
- The National Archives introduces the records
An institutional guide describes its contemporary Flight 19 investigations and correspondence.
Activity 2: hold B fixed and change only A
Fix B’s total at 1,000 journeys. When A also has 1,000, the shares are A 3% and B 2%. Change only A to 3,000 and A becomes 1%, while B remains at 2%.
Counts remain A 30 and B 20, but the higher share switches sides. This exposes missing information in a comparison based only on counts. Every bar keeps the same 0–4% range, with readable fractions and percentages beside it.
Separate unresolved details from missing comparison data
Respecting the records of real losses is compatible with questioning claims about an entire sea area. Uncertainty about one event’s cause does not establish an unusually high regional frequency.
Nor do these fictional A/B calculations establish a real sea area’s safety. Real comparisons need matching definitions, periods, boundaries and journey data, with conditions such as routes, weather and vessels also examined. Keep this question: how many incidents, out of how many journeys?
Put journey totals beside incident counts
Compare fictional fractions and percentages to find what a count-only comparison leaves out.
Compare totals and sharesSources and scope
Based on NOAA’s Bermuda Triangle explanation and the U.S. National Archives guide to Flight 19 records. Institutional statements about boundaries and frequency remain distinct from documented individual losses. We have not compiled an exhaustive real incident-and-traffic dataset.
