France's Consul Raphael Trannoy (3rd R) talks to members of the forensic experts team sent by the French government as they arrive at La Rioja airport March 13, 2015. France mourned on March 10 the deaths of three sports stars who were among 10 people killed when two helicopters collided in a remote region of Argentina during the filming of a reality TV show. Investigators removed the bodies of Olympic swimmer Camille Muffat, yachtswoman Florence Arthaud and boxer Alexis Vastine from the charred wreckage of the two aircraft, but said it was still unclear what caused the accident on Monday afternoon in the rugged western province of La Rioja.
