The president of the French Swimming Federation (Federation Francaise de Natation), Francis Luyce, has expressed his horror after learning of the death of Camille Muffat.
The 25-year-old was one of 10 people, including three Olympians, to lose their lives when two helicopters collided on a French reality television show in Argentina.
Speaking to L'Equipe, FFN president Luyce said: "I am horrified, it is beyond comprehension.
"The swimming family has lost one of its most loved ones, one of its greatest swimmers. I keep a picture of a radiant Camille - she was happy and deserved to be. Rarely in my life have I been as troubled as today."
Muffat retired from competitive swimming last year after winning Olympic gold in the 400m freestyle at London 2012.
