PANGKALAN BUN, Indonesia -- A tail section from the AirAsia plane that crashed into the Java Sea late last month, killing all 162 people on board, became the first major wreckage lifted off the ocean floor Saturday, but the all-important black boxes were not found inside.

The red metal chunk, with the words "AirAsia" clearly visible across it, was brought to the surface using inflatable balloons.

The cockpit voice and flight data recorders, located in the plane's rear, must have detached when the Airbus A320 plummeted into the waters Dec. 28, said Indonesian military commander Gen. Moeldoko. Their recovery is essential to finding out why Flight 8501 crashed.

However, Moeldoko, who like many Indonesians uses only one name, said pings believed to be coming from the black boxes were detected Saturday. Their beacons emit signals for about 30 days until the batteries die, meaning divers have about two weeks left to find them.

"I am fully confident that the black boxes are still not far from the tail," Moeldoko said

The debris was brought up from a depth of about 100 feet and towed to a ship, where it was hoisted onto the deck. The vertical stabilizer was still largely intact, but the attached jagged fuselage was ripped open and tangled by a mess of wires.

The tail's discovery earlier in the week was a major breakthrough in the slow-moving search, which has been hampered by seasonal rains, choppy seas and blinding silt from river runoff.

But Suryadi Bambang Supriyadi, operation director of Indonesia's national search and rescue agency, said Saturday that he was still focused on finding the main section of fuselage, where most of the bodies are believed to be entombed. Several large objects have been spotted in the area by sonar, but they have not yet been explored underwater. So far, only 48 corpses have been recovered.

"This is what the families have been waiting for," Supriyadi said. "They have been crying for 14 days."

"I'm very concerned that we didn't find the main body of the plane, because I believe the bodies of the majority of the victims are trapped in there," Moeldoko told reporters, according to Reuters.

The last contact the pilots had with air traffic control, about halfway into their two-hour journey from Indonesia's second-largest city, Surabaya, to Singapore, indicated they were entering stormy weather. They asked to climb from 32,000 feet to 38,000 feet to avoid threatening clouds, but were denied permission because of heavy air traffic. Four minutes later, the plane dropped off the radar. No distress signal was issued.

Meanwhile, Transportation Minister Ignasius Jonan cracked down on five airlines Friday, temporarily suspending 61 flights because they were flying routes on days without permits. Earlier, all AirAsia flights from Surabaya to Singapore were stopped after it was discovered that the low-cost carrier was not authorized to fly on Sundays.

Jonan also sanctioned nine more officials for allowing the AirAsia plane to fly without permits, bringing the total to 16.
