The Story

On March 8, 2014, Flight MH370 ceased transponder communications during an air traffic handoff between Malaysia and Vietnam. Primary military radar tracked the aircraft turning sharply southwest back over the Malay Peninsula. Satellite data proved the aircraft flew for over six hours toward the southern Indian Ocean before running out of fuel.

Timeline

  1. Flight MH370 departs Kuala Lumpur; signs off at 01:19 AM and vanishes from civilian tracking two minutes later.

  2. A section of the aircraft's wing flaperon is found on a beach on Réunion Island in the western Indian Ocean.

  3. Ocean Infinity concludes its secondary high-tech autonomous underwater vehicle search without locating the wreckage.

Known Evidence

Evidence strength

How well-documented and physically verified the case evidence is.

  • Seven automated, hourly satellite communication handshakes logged by the Inmarsat network after secondary radar went dark.
  • Primary military radar data capturing a sharp, manual tactical turn over the South China Sea requiring direct pilot input.
  • An abrupt Satellite Data Unit (SDU) power interruption between 01:07 and 02:03, followed by an anomalous network log-on reboot at 02:25.
  • A confirmed right-wing flaperon and structural internal composite panels washing ashore on Réunion Island and East African coasts.

Unresolved

What We Still Don't Know

  • The exact geographic location of the main fuselage, flight data recorders, and cockpit voice recorders on the ocean floor.
  • The definitive operational motive behind the total manual deactivation of the aircraft's transponder and ACARS communication buses.
  • The physiological state of the flight crew and passengers during the final six-hour southbound leg across the Indian Ocean.

Hypotheses

Theories

Ranked by plausibility — highest first.

Most plausible
Plausibility

Pilot Rogue Command Execution

The captain or first officer locked the other out of the flight deck, deliberately killed the communications systems, depressurized the cabin to neutralize resistance, and flew a pre-planned route to fuel exhaustion.

Theory 2
Plausibility

Sudden Decompression and Ghost Flight

An unforeseen structural failure, cockpit fire, or toxic outgassing forced the pilots to alter course toward an emergency landing strip, before hypoxia incapacitated the crew and left the aircraft on autopilot.
