Reports over the weekend said that the batteries of the missing jet black box are likely empty by now. There has not been a new ping received since days. Today officials said according to Reuters, that the search effort is going into a new phase. A United States Navy submarine drone will be sent to the floor of the Indian Ocean.
The search for the missing Malaysian airline black box is now mostly relying on the the Blue-fin 21 autonomous sub. The sub can search the ocean floor for wreckage about up to 2.8 miles beneath the surface.
The Malaysian airlines flight MH370 went missing March 8. Over a month later search teams only picked up four ping signals that are believed to originate from the jet's black box. It is still mind boggling that no debris of the plane has been found so far. The search with the sub drone is a needle in the haystack effort and will take a long time.
