The pings have officially gone silent. The Boeing 777's black box of the missing Malaysia Airlines Flight 370 may be dead.
Four pings were consecutively heard last week, as the extensive search was finally narrowed down to a 500-square-mile area of the Indian Ocean.
"A Bluefin 21 submersible will be deployed to scour the sea floor only when officials are certain no more electronic signals will come," reports Time. "The submersible, which takes six times longer to cover the same distance as the Ocean Shield’s ping locator, will require between six weeks to two months to search the underwater zone."
A typical black box battery lasts 30 days. MH370 vanished on March 8.
