Searchers in India Wednesday recovered the flight recorders from the two planes which crashed Tuesday, killing 349 people.
Aviation experts hope they will provide clues to why the Saudi Airlines Boeing collided with the Kazakh Ilyushin Il-76 cargo plane near Delhi.
All Wednesday, rescuers combed the debris of the crash site, searching for passengers' bodies.
The world's worst mid-air crash created an horrendous sight - charred bodies, clothes and personal effects strewn across a wide area.
Soldiers searched the debris for clues to identify bodies.
Many of the victims were apparently Indian workers returning to jobs in the Middle East or making the Muslim pilgrimage to Mecca.
Doctors said no one could have lived through the collision that turned the two aircraft into fireballs, incinerating many of the passengers before they had even hit the ground
Grieving relatives went to makeshift morgues to try to identify the remains of their loved ones.
Most of the victims were badly burned or mangled, lying on blocks of ice and covered in sheets.
Miraculously, people living in these villages near the crash site were not hit.
Local residents are sure the pilot of the jumbo averted an even worse disaster by steering his doomed aircraft away from their villages.
The flight data and cockpit voice recorders were picked out of the debris, Wednesday.
Aviation experts hope they will provide clues as to why the Saudi Airlines Boeing collided with the Kazakh Ilyushin Il-76 cargo plane near New Delhi.
Indian aviation authorities say they have ruled out the possibility their air traffic control was at fault.
"Whatever the air traffic controller did was absolutely right, he informed the two aircraft what was the distance separating them, he told them watch out for the aircraft that was coming, he told them the vertical distance that was separating them, everything was according to the guidelines."

British aircrash investigator and former pilot John Guntrip believes regulations will have to be tightened up as a result of the collision.
"There will certainly be a lot of lessons to be learnt. They may have to tighten up regulations, they may have to bring forward the introduction of more advanced radars, and also they may well insist on bringing forward T-CAS which is an American collision- avoidance system which is fitted. It's mandatory now for all aircraft flying in the United States and because it's mandatory over there, a lot of the European airlines British Airways, Britannia Airways have fitted this to their aircraft, and if you have two aircraft which are going to come too close together and they've both got transponders, the transponders can listen to each other and one of them will decide to instruct the pilot to dive or climb about a thousand feet to avoid a collision.

The new equipment may push up the price of flying, but with the number of planes in the air increasing year by year, it may be the only way to prevent this happening again.
