On March 8, 2014, Malaysian Airlines flight MH370 vanished from radar less than an hour into a routine run from Kuala Lumpur to Beijing, taking 239 people with it. This film reconstructs the flight's last known movements, the sudden course change away from its filed route, and the satellite handshake data that investigators later used to estimate a search zone in the remote southern Indian Ocean. It walks through the multinational hunt that followed, ships and aircraft combing tens of thousands of square miles of open water in what became one of aviation's largest and costliest search operations, and the scattered debris, including a flaperon washed up on Réunion Island, that eventually confirmed the crash without explaining it. Investigators, aviation analysts, and search-team figures lay out the competing theories, mechanical failure, hijacking, deliberate pilot action, against the plain fact that a modern airliner equipped with tracking systems still disappeared. The film stays with the unresolved core of the case: no wreckage of the main fuselage, no black boxes recovered, and no settled account of what happened in the cockpit.
