Ahmednagar/ New Delhi, March 25 (ANI): After the declaration made by Malaysian Prime Minister Najib Razak about the crash of missing Malysian flight MH370 in Southern Indian Ocean, relatives of the passengers in India mourn over the death of their kin. The relatives express shock as well as anger at the news saying that in this world of technology, it is hard to believe that a Boeing plane can go missing. Meanwhile, retired Rear Admiral K Raja Menon expressed doubt over the statement of plane crash as there has been no valid proof for it. The launch of an official air crash investigation would give Malaysia power to coordinate and sift evidence, but it may still face critics, especially China, which had more than 150 citizens on board the missing plane and has criticised Malaysia over the progress of the search.
