Malaysia Airlines Flight 370 disappeared on 8 March 2014, after departing from Kuala Lumpur for Beijing, with 227 passengers and 12 crew members on board. Malaysia's former Prime Minister, Najib Razak, stated that the aircraft's flight ended somewhere in the Indian Ocean, but no further explanation had been given. Despite searches finding debris considered with strong certainty to originate from the crash, official announcements were questioned by many critics, and several theories about the disappearance were proposed. Some of these theories were described as conspiracy theories.
