Australian Prime Minister , Tony Abbott , at the weekend said the signal from the plane’s black boxes Malaysia Airlines MH370 , will likely continue extinguished quickly . Therefore, the predicted black box battery can only last for 30 days .
While entering the 37th day , the search process is still not yielded positive results . Quoted from page Times of India , Sunday, April 13 , Board Joint Coordination Center ( JACC ) said joint rescue operation that was held yesterday involving 11 military aircraft , the civilian aircraft and 14 ships .

While focused search area reached 2,200 kilometers northwest of Perth , Australia . They began to narrow the search area is located in the Indian Ocean in order to mobilize the vehicle to detect the underwater wreckage .
In the search mission , said JACC , Australian defense ship , Ocean Shield , continue to focus on combing using a tracking device signal black box , Towed Pinger Locator , to catch other signals . Therefore , it had been four days they have not managed to catch the new ping signal .
China also does not want to miss , because they are also planning to deploy underwater vehicles made their own sake can be found debris Boeing 777-200 ER .
Then , when the black box battery is completely discharged , what’s the next step of a joint SAR team ? According to National Geographic oceanographer , Sylvia Earle , it’s time they should deploy underwater vehicles belonging to the United States , the Bluefin - 21 , to comb the sea level and not just listen to the ping signal black box .
"This thing can help find the location of the wreckage , " said Earle told CNN .
With the tools , ships at sea can find a picture of the terrain beneath instead of using the camera but from the sound . After the wreckage was found , other tools such as remote operating vehicle ( ROV ) must also be deployed to find the black box . ROV capable of combing to a depth of three miles under the sea .
The problem , said Earle , to deploy the ROV , it takes a cable from the ship at the sea surface .
" Not a lot of this kind of equipment available in the world , " he said .
Only a few countries have such submarines of the United States , Russia , Japan , China and France alone which can be lowered at that depth .
"In addition , the presence of human presence in the underwater will certainly make a big difference . You know very little about what was in there , " said Earle .
However , from this incident , said Earle , helped give rise to the wisdom that is how they invest a lot of funds for aviation and aerospace industry , but even ignoring the marine industry .
While in the eyes of Flight Analysis of CNN , David Soucie , not be a surprise if the search has not been fruitful plane positively to this day . It could happen , because the search model used to track debris mistaken .
According to the author of a book titled ” Why Planes Fall ” , reflecting from a plane crash of Air France 447 that crashed in the South Atlantic Ocean in 2009 ago due to one thing .
" They spent a week to look for the presence of debris in the wrong location , " said Soucie .
Moreover , according to him , not until the discovery of the wreckage could mean the 37th aircraft could not be destroyed but rather fall to the ocean floor in a state of plane parts still intact . If that happens , then the process of finding the black boxes require extra effort , because they are located in the tail .
Investigators had to disassemble the tail to take the black box and unpack the mystery of the cause of the loss of military radar plane mysteriously on March 8, 2014 , then . ( eh )
