Summary

Malaysia Airlines flight MH370 took off from Kuala Lumpur heading for Beijing on March 8, 2014 — and vanished.Now, nearly 12 years later, a new search is set to begin.Is the new search likely to find new evidence more than a decade after the flight went missing? And with satellite technology how does a commercial aircraft disappear? This is what we know.'Goodnight, Malaysian three seven zero'The disappearance of flight MH370 with 239 people on board remains one of the world's most baffling aviation mysteries.The Boeing 777 went missing on its way from Kuala Lumpur to Beijing on March 8, 2014. There were seven Australians, more than 150 Chinese and 50 Malaysians on the flight, as well as citizens of France, Indonesia, India, the United States, Ukraine and Canada.A US-based marine robotics company will be paid $110.2 million if it locates the wreckage in a new search area in the southern Indian OceanSatellite data analysis showed the plane most likely crashed somewhere in the southern Indian Ocean, off the coast of Western Australia. However, two major searches failed to come up with any significant findings.The last radio transmission from the plane was about 40 minutes after it took off.
