In addition to the erratic weather condition that prevails over the area, the teams of deep sea divers find it hard to access the bottom of the ocean due to strong undersea currents.
The search teams have already found the location of the main wreckage of the aircraft where most of the remains are believed to have been trapped inside.
According to the search and rescue agency director, Suryadi B. Supriyadi, the 15 divers were having a hard time reaching the depth of more than 90 feet due to the undersea currents which were dangerously strong. They attempted to reach the main wreckage, but unsuccessful. They need to examine it at close range and calculate its weight in order to know what sort of equipment needs to be used, or how they are going to retrieve the object in the easiest way.
The survey vessels have also identified at least 9 big objects which, they believe, belong to the ill-fated aircraft. These include the fuselage and parts of the cockpit. Without divers actually seeing it up close, they could not confirm for sure if the objects really belong to QZ8501.
They believe that the fuselage holds most of the victims, which are still trapped to their seats. After the recovery of the two flight recorders a week ago, the teams now focus on the retrieval of the victims' remains.
So far, the teams have retrieved a total of 53 bodies, 45 of which have already been identified.
The country's Disaster Victim Identification Police Department is tasked to do the job in identifying all the bodies recovered from the crash through DNA samples.
A full-blown investigation has been ongoing in Jakarta led by the Transport Ministry since the recovery of the two flight recorders, the flight data recorder (FDR) and the cockpit voice recorder (CVR) on January 14.
AirAsia Indonesia flight QZ 8501 was cruising on an altitude of 32,000 feet when it reportedly encountered bad weather on a fateful Sunday morning of December 28, 2014 before it crashed into the Java Sea.
