Three French athletes are among 10 dead in a helicopter crash in Argentina that took place while filming for a reality TV show, according to reports.
Eight French nationals and two Argentinian pilots were killed when two helicopters collided in La Rioja province in Argentina's northwest region. Olympic swimmer Camille Muffat, 25, Olympic boxer Alexis Vastine, 28, and sailor Florence Arthaud, 57, died in the crash. Both helicopters were part of the reality TV show Dropped.
Muffat had won three medals, including gold in the 400m freestyle in the 2012 London Olympics. Vastine took home the bronze medal from the 2008 Beijing Olympics, while Arthaud won the 1990 Route du Rhum, the prestigious solo Atlantic race.
Dropped, which aired on TF1, flies blindfolded celebrities into rough terrain via helicopter and follows them while they attempt to find food and shelter as they make their way back to civilization.
"The sudden death of our fellow French nationals is a cause of immense sadness," French President François Hollande said in a statement, per BBC News.
France's prime minister, Manuel Valls, tweeted, "All France is grieving this morning."
Another contestant on Dropped, French soccer player Sylvain Wiltford, tweeted, "I'm sad for my friends, I'm trembling, I'm horrified, I have no words, I don't want to say anything."
"We learn with great sadness about the accident during the filming of the Dropped show," said a statement issued by TF1, according to BBC News. "All TF1 teams come together in this terrible time with the pain of the families and relatives of the victims."
Dropped has been postponed and the rest of the crew is reported to be returning home.
This was the second time in two years that a reality TV show for TF1 was struck by tragedy. In April 2013, a contestant died following an on-screen challenge for France's longest-running reality show, Koh-Lanta. The show's doctor was later found dead in his hotel room, leaving behind a suicide note that said his name and reputation had been sullied and he could no longer stand the media pressure.
