PARIS -- Three French athletes were among the 10 people who died as two helicopters filming a reality show crashed in a remote part of Argentina on Monday.

Here's a brief look at the careers of the three prominent French athletes killed in the helicopter crash:

CAMILLE MUFFAT

Camille Muffat won the gold medal in the 400-meter freestyle at the 2012 London Games, setting an Olympic record. She added a silver medal in the 200-meter freestyle and a bronze in the 4x200 freestyle relay to become only the third Frenchwomen - including swimmer Laure Manaudou - to win three medals in the same games. Muffat, who was 25 and grew up in the southern French city of Nice, was also a four-time world bronze medalist. She retired from swimming last year to focus on her personal life.

ALEXIS VASTINE

Alexis Vastine won a bronze medal in boxing at the 2008 Olympics in Beijing after a controversial loss to Manuel Felix Diaz of the Dominican Republic in the semifinals. Vastine was ahead in the bout but was docked points by the referee in the final round. He broke down in tears after the defeat. There were tears again at the London Games four years later when he drew on points with Taras Shelestyuk of Ukraine in the quarterfinals, but lost on the count-back rule. The 28-year-old Vastine had vowed to win Olympic gold next year in Rio de Janeiro.

FLORENCE ARTHAUD

Florence Arthaud, who was 57, was a pioneer in sailing. In 1990, she became the first woman to win the famed Route du Rhum race - a trans-Atlantic single-handed yacht race between Brittany and the Caribbean island of Guadeloupe - on her boat Pierre 1er. Her success made her an overnight star and she won the "Champion of Champions" award given each year by sports daily L'Equipe. She had impressed in her first appearance in the race in 1978, placing 11th. In the 1986 edition of the Route du Rhum, she overlooked her own ambitions and went out of her way to help a stricken colleague at sea.
