Almost all of them. The "Star Tiger" disappeared on a flight to Bermuda in January, 1948, and a Douglas DC-3 disappeared in December that same year. A training flight of bombers went missing in 1945, possibly in the area of the triangle. There are dozens of flights over the "Bermuda Triangle" every day, and in the past 80 years these are about the only unexplained disappearances--all of which occurred more than 60 years ago. Oh, a Cessna disappeared in 1969. Statistical analysis has shown that any equally heavily traveled area of ocean has about the same (or more) "unexplained" disappearances as the Bermuda Triangle. Disappearances there are not statistically significant.
