A sad case. Once they find the data boxes and inspect the data and voice records of the crew they might arrive at an answer. Unlike the USA, India as well as China prioritise political aspects above facts. This leads to the danger of hidden facts that show any officer is at fault. They also have a rigid hierarchy so if a senior officer makes an error, a junior officer dares not correct him and cause the senior to lose 'face'. This has caused plane crashes in India/China in the past.
