Misi mencari pesawat MH370 diteruskan di Selatan Lautan Hindi, satu kawasan yang sangat jauh daripada daratan dan mempunyai ekosistem dan arus lautan yang tidak kondusif dan amat berbahaya.
Terbaru ialah penemuan hampir 300 objek di kawasan tersebut oleh satelit negara Thailand. Sebelum ini, satelit Airbus Defence & Space menemui 122 objek, 2,557 km daripada Perth, Australia. Baca Sini.
Sekarang, satu peralatan Tentera Laut USA sudah tiba di Perth, Australia untuk membantu mencari peti black box pesawat MH370.

U.S Navy Fact Sheet
Towed Pinger Locator 25
Description
The TPL-25 System meets the Navy’s requirement for locating emergency relocation pingers on downed Navy and commercial aircraft down to a maximum depth of 20,000 feet anywhere in the world.
Features
The system consists of the tow fish, tow cable, winch, hydraulic power unit, generator, and topside control console, although not all of these components are required on every mission. Navigation is accomplished by using algorithms incorporating the amount of cable in the water, the depth indication from the pressure sensor and other parameters.
The generator provides electrical power for the system or power from the support platform can be used if it is compatible. The tow fish carries a passive listening device for detecting pingers that automatically transmit an acoustic pulse.
Most pingers transmit every second at 37.5 kHz, although the TPL can detect any pinger transmitting between 3.5 kHz and 50 kHz at any repetition rate. Commercial aircraft pingers are mounted directly on the flight recorder, the recovery of which is critical to an accident investigation.
The Pinger Locator is towed behind a vessel at slow speeds, generally from 1 - 5 knots depending on the depth. The received acoustic signal of the pinger is transmitted up the cable and is presented audibly, and can be output to either a Oscilloscope, or Signal Processing Computer.
The operator monitors the greatest signal strength and records the navigation coordinates. This procedure is repeated on multiple track lines until the final position is triangulated. The current TPL-25 replaces all previous systems; TPL-20, 30, & 40.

Similar technology was used to locate the main wreckage from Air France flight 447 in 2011 – yet it still took searchers two years to recover the black box from the depths of the Atlantic.Bagaimana pun, rakyat terutamanya keluarga penumpang dan krew MH370 perlu tahu bahawa pakar-pakar oceanografi telah mengatakan betapa sukarnya misi mencari pesawat MH 370 di Selatan Lautan Hindi :
Experts said search crews faced significant dangers due to frequent bad weather and the area's distance from land.
"This is a really rough piece of ocean, which is going to be a terrific issue," Kerry Sieh, director of the Earth Observatory of Singapore, told Associated Press.
"I worry that people carrying out the rescue mission are going to get into trouble."
Dalam masa yang sama, media barat terus dikecam kerana berat sebelah dan sengaja memburuk-burukkan nama baik negara Malaysia.
