Scientific theories, meanwhile, include pilot error when trying to navigate the area, and huge “rogue waves” caused by terrible storms. Although many ships and planes cross the Bermuda Triangle without incident, the stories behind those doomed vessels’ fates continue to capture people’s imaginations.
