Buenos Aires: A helicopter which was being used for filming an MTV reality show has crashed into a reservoir in Argentina killing the pilot and a technician.
The aircraft came down at the Potrerillos de Mendoza dam in western Argentina, officials said. MTV said the helicopter was flying to a shooting location for the show The Challenge.
Neither of those killed was a cast or film crew member, the US channel said, and no-one else was on board. Divers were having difficulty finding the bodies, the security minister for Mendoza province, Gianni Vernier, told.
The wreckage lies at a depth of 60m (200ft). It was the second fatal crash of a helicopter involved in a reality TV show this year in Argentina.
The helicopters were involved in the filming of the TV survival show Dropped.
