Air France Flight 447 - Air crash bodies heading to DNA lab

The first bodies to be recovered from the crash of Air France 447 are due to arrive at a Brazilian Air Force base in Recife, Brazil, Wednesday afternoon local time, the air force announced.

The 16 bodies are expected to be sent on for identification to the Legal Medical Institute, the statement said. Police will perform DNA tests at their lab in the capital, Brasilia, they said.

Another 25 bodies have been found and will go through the same procedure starting Thursday, the air force said.

A French nuclear submarine joined the hunt Wednesday for the "black box" flight data recorder and other wreckage of Air France Flight 447 as Brazilian air force and navy crews continued to pull bodies from the Atlantic.

France is leading the investigation into what caused last week's accident when the Paris-bound flight from Rio de Janeiro plunged into the sea off the Brazilian coast with 228 passengers and crew on board.

The French nuclear submarine Emeraude began patrolling the area Wednesday morning, the French defense ministry said.

Around 400 French military personnel are involved in the salvage effort. France has also sent two tugs towing 40 tons of recovery equipment, a surveillance ship and a ship equipped for amphibious operations.

Fourteen aircraft -- 12 Brazilian and two French -- are participating, along with five Brazilian ships. The U.S. Navy will contribute two high-tech acoustic devices to listen underwater for the emergency beacons that are attached to the voice and data recorders.

The "towed pinger locators," which help search for emergency beacons on downed aircraft to a maximum depth of 6,000 meters (20,000 feet) -- will be placed aboard the French tugs.
