Rescue crews lifted the tail section of AirAsia Flight 8501 from the bottom of the Java Sea today, but the black boxes were not found inside.

The black boxes could hold the answer to why the plane crashed into the sea late last month, killing all 162 people on board.

Bryan Llenas reported on "America's News Headquarters" today that Indonesian authorities were hoping the cockpit voice and flight data recorders would be where they were supposed to be, in the tail of the plane.

"Inflatable balloons were used to bring the plane's red tail to the surface today, and authorities say the black boxes must have detached on impact," Llenas said.

He added that search boats have detected several pings near where the tail was located and those pings could be the boxes.

"Now, timing is everything. The batteries on those beacons emitting pings from the black boxes only last about 30 days, which means divers have about two weeks left to locate them," Llenas said.

Llenas added that of the 162 people onboard, only 48 bodies have been found.

"Investigators believe that the majority of the victims are located in the main body of the airplane about 100 feet below the ocean," he said, noting that authorities have promised to continue the search until all remains are found.

"Meanwhile, sonar continues to detect more objects in the area, including what's believed to be the plane's front section."
