Malaysia Airlines Flight 370

Malaysia Airlines flight 370 disappearance, also called MH370 disappearance, disappearance of a Malaysia Airlines passenger jet on March 8, 2014, during a flight from Kuala Lumpur to Beijing. The disappearance of the Boeing 777 with 227 passengers and 12 crew members onboard led to a search effort stretching from the Indian Ocean west of Australia to Central Asia. The perplexing nature of the loss of flight 370 is such that it has become one of history’s most famous missing aircraft.

Flight 370 took off at 12:41 AM local time and reached a cruising altitude of 10,700 meters (35,000 feet) at 1:01 AM. The Aircraft Communication Addressing and Reporting System (ACARS), which transmitted data about the aircraft’s performance, sent its last transmission at 1:07 AM and was subsequently switched off. The last voice communication from the crew occurred at 1:19 AM, and at 1:21 AM the plane’s transponder, which communicated with air-traffic control, was switched off, just as the plane was about to enter Vietnamese airspace over the South China Sea. At 1:30 AM Malaysian military and civilian radar began tracking the plane as it turned around and then flew southwest over the Malay Peninsula and then northwest over the Strait of Malacca. At 2:22 AM Malaysian military radar lost contact with the plane over the Andaman Sea. An Inmarsat satellite in geostationary orbit over the Indian Ocean received hourly signals from flight 370 and last detected the plane at 8:11 AM.

Initial searches for the plane concentrated on the South China Sea. After it was determined that flight 370 had turned to the west shortly after the transponder was switched off, search efforts moved to the Strait of Malacca and the Andaman Sea. On March 15, a week after the plane had disappeared, the Inmarsat contract was disclosed. Analysis of the signal could not locate the plane precisely but did determine that the plane might have been anywhere on two arcs, one stretching from Java southward into the Indian Ocean southwest of Australia and the other stretching northward across Asia from Vietnam to Turkmenistan. The search area was then expanded to the Indian Ocean southwest of Australia on the southern arc and Southeast Asia, western China, the Indian subcontinent, and Central Asia on the northern arc. On March 24 Malaysian Prime Minister Najib Razak announced that, based on an analysis of the final signals, Inmarsat and the U.K. Air Accidents Investigation Branch (AAIB) had concluded that the flight crashed in a remote part of the Indian Ocean 2,500 km (1,500 miles) southwest of Australia. Thus, it was extremely unlikely that anyone on board survived. 

The search for wreckage was hampered by the remote location of the crash site. Beginning on April 6, an Australian ship detected several acoustic pings possibly from the Boeing 777’s flight recorder (or “black box”) about 2,000 km (1,200 miles) northwest of Perth, Western Australia. Further analysis by the AAIB of the Inmarsat data also found a partial signal from the plane at 8:19 AM consistent with the location of the acoustic pings, the last of which was heard on April 8. If the signals were from flight 370, the flight recorder was likely at the end of its battery life. Further searches were conducted using a robotic submarine. However, the pings had been spread over a wide area, the submarine found no debris, and tests found that a faulty cable in the acoustic equipment could have produced the pings.

In the weeks following flight 370’s disappearance, theories ranged from mechanical failure to pilot suicide. The loss of the ACARS and transponder signals spurred ongoing speculation about some form of hijacking, but no individual or group claimed responsibility, and it seemed unlikely that hijackers would have flown the plane to the southern Indian Ocean. That the signals had likely been switched off from inside the aircraft suggested suicide by one of the crew—a possibility that Malaysian authorities have yet to rule out—but nothing suspicious was found in the behavior of the captain, the first officer, or the cabin crew prior to the flight. After the discovery of the debris, some speculated that flight 370 was shot down, but no evidence of shrapnel from a missile or other projectiles has been found. 

The Bermuda Triangle Theory

 

What is the Bermuda Triangle?

For decades, the Atlantic Ocean’s fabled Bermuda Triangle has captured the human imagination with unexplained disappearances of ships, planes, and people.

Some speculate that unknown and mysterious forces account for the unexplained disappearances, such as extraterrestrials capturing humans for study; the influence of the lost continent of Atlantis; vortices that suck objects into other dimensions; and other whimsical ideas.  Some explanations are more grounded in science, if not in evidence.  These include oceanic flatulence (methane gas erupting from ocean sediments) and disruptions in geomagnetic lines of flux.

Environmental considerations could explain many, if not most, of the disappearances.  The majority of Atlantic tropical storms and hurricanes pass through the Bermuda Triangle, and in the days prior to improved weather forecasting, these dangerous storms claimed many ships.  Also, the Gulf Stream can cause rapid, sometimes violent, weather changes.  Additionally, the large number of islands in the Caribbean Sea creates many areas of shallow water that can be treacherous to ship navigation. And there is some evidence to suggest that the Bermuda Triangle is a place where a “magnetic” compass sometimes points towards “true” north, as opposed to “magnetic” north. 

The U.S. Navy and U.S. Coast Guard contend that there are no supernatural explanations for disasters at sea.  Their experience suggests that the combined forces of nature and human fallibility outdo even the most incredulous science fiction. They add that no official maps exist that delineate the boundaries of the Bermuda Triangle. The U. S. Board of Geographic Names does not recognize the Bermuda Triangle as an official name and does not maintain an official file on the area.

The ocean has always been a mysterious place to humans, and when foul weather or poor navigation is involved, it can be a very deadly place.  This is true all over the world.  There is no evidence that mysterious disappearances occur with any greater frequency in the Bermuda Triangle than in any other large, well-traveled area of the ocean.
