Civil aviation experts in the US believe that the plane carrying 239 people onboard could have vanished for ever if it was hit by fire, a bomb, hijack or catastrophic decompression and swallowed up in millions of square miles of ocean.
However, Congressman Mike Rogers said that accepting that the Flight MH370 might never be found was likely to become a whole new window of this investigation and it might lead to the biggest dead end of all that the plane is at the bottom of the Indian Ocean, express.co.uk reports.
The Flight MH370 disappeared from civilian radar on March 8th just 40 minutes after take off from Kuala Lumpur enroute to Beijing.
The desperate search for the plane led to a lot of theories emerging in the plane's mysterious disappearance, including hijack, sea crash, pilot suicide and Bermuda Triangle-like situation.
Since 11 days, authorities haven't been able to trace any debris of the presumed crash, or found any possible terror links of the passengers or crew on board.
Billie Vincent, former security chief of the US Federal Aviation Administration, said that he believed the crew fought in vain to save the plane after fire broke out in the cargo hold.
Meanwhile, Malaysian Prime Minister Najib Razak, stress in a press conference last week that the plane's communication systems were deliberately turned off by some one on board.
However, he didn't confirm if the plane was hijacked or crashed into the sea, but stressed that their focus remains on finding the passengers and the crew.
