The mystery of the missing Malaysia Airlines Flight 370 has yet to be solved.
The search continues for the black box, which will hopefully help locate the missing plane.
Officials are having a difficult time searching for the black box as the area the plane could have crashed in the southern Indian Ocean still hasn't been specified.
According to The Wall Street Journal, there are less than two days remaining until the black box runs out of battery, which means that it will be almost impossible to find flight 370 at all.
The search has shifted under water for the first time on Friday as two naval vessels from Australia and the U.K. began probing the ocean depths.
The Australian ship, Ocean Shield, is equipped with a U.S. device designed to detect signals from the flight records, which is thought to be sitting up to 2 ½ miles below the surface.
It has been reported that if something is not found this weekend, more hope may be lost in terms of the search.
China, Malaysia and Australia may be the three countries that won't be able to back out of the search at all for political and diplomatic reasons.
China has 153 citizens on board Malaysia Airlines Flight 370 while Malaysia is legally bound to investigate the disappearance as the home country of the airline.
It wouldn't be a wise decision for Australia to back out either because the search has now shifted to its maritime backyard.
China's Premier Li Keqiang said to Australian Prime Minister Tony Abbott on the phone, "Although search efforts face increasing complications and difficulties, they should not be relaxed, much less abandoned."
Abott has said to the public, "If this mystery is solvable, we'll solve it."
For now, other countries involved in the search include Japan, South Korea and New Zealand. All three countries have reportedly pledged ongoing support.
According to CBS News, although Australia, the U.S., Britain and China have agreed to be "accredited representatives" of the search, the investigation into the plane's disappearance ultimately remains Malaysia's responsibility.
Our thoughts go out to the families and friends of the passengers of Flight 370.
