Australian and Chinese ships have already detected three separate signals which are believed to be from the crashed MH370 black box. This raises the hopes of solving one of the biggest mysteries in the aircraft history. The most promising lead so far still needs to be confirmed. The signals, that have been detected, are consisted with the ones emitted by black box of an aircraft.
On Saturday, Haixun 01, Chinese vessel, has detected two pulses which are an "important and encouraging lead." The vessel remains in position in attempt to regain the signals. HMS Echo, British naval vessel, has been dispatched to assist the Haixun 01.
The third signal was detected on Sunday by Ocean Shield 300 nautical miles away Haixun 01. The sounds were heard at a 4,500-metre depth. The first detection was held for 2 hours and a half, then Ocean Shield lost contact. After turning around, the pinger locator managed to pick the signal again for another 13 minutes. The frequency of the signals is believed to be 37.5 kHz.
The former defence chief of Australia, Angus Houston, leader of the search coordination body said:
"The towed pinger locator deployed from the Australian defence vessel Ocean Shield has detected signals consistent with those emitted from aircraft black boxes. We are encouraged that we are very close to where we need to be. The lead we've got at the moment is worth following through to the fullest extent."
Today, the search operation is being conducted by 12 planes (9 military and 3 civilian) and 14 vessels. The ships and aircraft, deployed to the area, are trying to identify whether the signals are from MH370's black box.
