Debris from MH370 discovered on Réunion Island

What was Debris from MH370 discovered on Réunion Island?

Malaysia Airlines Flight 370 (MH370 / MAS370) was an international passenger flight operated by Malaysia Airlines that disappeared from radar on 8 March 2014 while flying from Kuala Lumpur International Airport in Malaysia to its planned destination, Beijing Capital International Airport in China, killing 239 passengers and crew members. The cause of its disappearance has not been determined. It is widely regarded as the greatest mystery in aviation history. The crew of the Boeing 777-200ER, registered as 9M-MRO, last communicated with air traffic control (ATC) around 38 minutes after takeoff when the flight was over the South China Sea.

The aircraft was lost from ATC's secondary surveillance radar screens minutes later, but was tracked by the Malaysian military's primary radar system for another hour, deviating westward from its planned flight path. It left radar range 200 nautical miles (370 km; 230 mi) west-northwest of Penang Island in northwestern Peninsular Malaysia. With all 227 passengers and 12 crew aboard presumed dead, the disappearance of Flight 370 was the deadliest incident involving a Boeing 777, the deadliest of 2014, and the deadliest in Malaysia Airlines' history until it was surpassed in all three regards by Malaysia Airlines Flight 17 on 17 July 2014.

Relying mostly on the analysis of data from the Inmarsat satellite with which the aircraft last communicated, the Australian Transport Safety Bureau (ATSB) initially proposed that a hypoxia event was the most likely cause given the available evidence, although no consensus has been reached among investigators concerning this theory. At various stages of the investigation, possible hijacking scenarios were considered, including crew involvement, and suspicion of the aircraft's cargo manifest; many disappearance theories regarding the flight have also been reported by the media. The search for the missing aircraft became the most expensive search in the history of aviation.
