The modern legend of the bermuda triangle began soon after five navy planes (flight 19) vanished on a training mission during a severe storm in 1945. the planes have not been discovered, though they were thought to have been found by divers not far off the atlantic coast. however, a check of the tail numbers and serial numbers determined these were different planes. the most logical theory is that lead pilot lt. charles taylor's compass failed. the trainees' planes were not equipped with working navigational instruments. the group was disoriented and simply, though tragically, ran out of fuel. no mysterious forces were likely to have been involved other than the force of gravity on planes with no fuel. it is true that one of the rescue planes blew up shortly after take off, but this was likely due to a faulty gas tank rather than to any mysterious forces. which sentence best expresses the main idea of this paragraph?
