Champion sailor Florence Arthaud, Olympic gold medalist swimmer Camille Muffat and Olympic boxer Alexis Vastine were among those killed when two helicopters filming the survival series "Dropped" crashed into each other in the rugged mountains of north west Argentina.
"Apparently, the two helicopters collided as they were filming. There are no survivors," provincial spokesman Horacio Alarcon told AFP earlier.
Later on Tuesday video footage was released that shows the moment the two helicopters collided in mid-air before plunging towards the ground.
It is still not clear what caused the crash with provincial spokesman Horacio Alarcon saying the weather conditions were good.
Recovery teams arrive
Argentine recovery teams arrived Tuesday at the site of a helicopter collision to recover the bodies of 10 people, including French sports stars participating in a reality TV show.
Aviation experts made it to the crash site in a mountainous area northwest of Buenos Aires in the early hours, said Judge Virginia Illanes Bordon.
"In a short while we will begin the task of recovery of the bodies," she told TN News
'Sadness and emotion'

A statement from the Elysée Palace said President François Hollande learned about the deaths "with immense shock and emotion" and expressed "condolences and support" to the victims' friends and families.
"Immense sadness over this tragedy. The whole of France is in mourning today. Thoughts go to the families of the victims," tweeted French Prime Minister Manuel Valls.
