USA Today reports:
“.....Divers looking for the black boxes on Thursday were unable to make it past currents and 1-meter (3-foot) visibility, said Soelistyo.
He said efforts will be intensified Friday to lift up the tail — either by using lifting balloon or crane.
Ping-emitting beacons in the black boxes still have about 20 days of battery life, but high waves had prevented the deployment of ping locators, which are dragged by ships.
Six ships with ping locators were in the search area in the Java Sea, said Nurcahyo Utomo, an investigator of the National Commission for Transportation Safety.
Based on pictures taken by divers, he believed that the black boxes were still attached to their original location in the plane's tail.
"Once detected, we will try to find and lift up the black boxes as soon as possible," he said...."
