What happened to Malaysia Airlines Flight MH370?

What happened to Malaysian Airlines Flight MH 370 is now a big question. It remains a big mystery and the plane's debris is still to be located in the vast seas. We have the latest technology and satellites. Where has the plane disappeared? The theory of Bermuda Triangle is being cited. The entire path of the flight from Kuala Lumpur to Beijing should be searched. The possibility of hijacking is also being looked into. But why has there been no contact from the hijackers? The Interpol has already dismissed the terrorism angle. There is another fear - if the debris are not located within a month, then the battery of the black box will run out of power as there are reports that the Malaysian Airlines did not fit the black box with satellite transmitter in order to cut costs. Had it done so, the black box would have been able to send signals even without battery power. An official announcement is yet to be made if the plane has crashed. The only official information we have is that the flight is missing.
