Olympic gold medal swimmer Camille Muffat, Olympic boxer Alexis Vastine and sailor Florence Arthaud were among 10 killed in the collision over a remote area of Argentina, according to The Independent.
The remaining victims were identified as Laurent Sbasnik, Lucie Mei-Dalby, Volodia Guinard, Brice Guilbert and Edouard Gilles, as well as Argentine pilots Juan Carlos Castillo and Roberto Abate.
The cause of the crash remains unclear. La Rioja Secretary of Security, Cesar Angulo, told TN television: “An explosion occurred and it’s believed that they [the helicopters] collided.”
The sports stars were filming a European celebrity reality show called Dropped when the accident occurred. The show’s producers, Adventure Line Productions (ADL), released a statement confirming the 10 deaths. “All the ADL teams are devastated and share the deep pain of the families and loved ones they are in contact with,” it said. “We are in contact with the production teams on site (and) with the French and Argentine authorities. We will give more information as soon as possible,” the Independent reported.
