A helicopter crash in Argentina has left two dead, the AP reports. The helicopter, which contained the pilot and a technician, was traveling to a location for MTV’s show The Challenge when it crashed into a reservoir approximately 600 miles from Buenos Aires. A police representative told El Sol the helicopter was not authorized to travel over the dam, and the cause of the crash is still unknown. This is, unfortunately enough, the second reality show–connected helicopter crash in Argentina this year; in March, a pair of helicopters working on the French survivalist show Dropped collided mid-air in northwestern Argentina, killing all ten people aboard. The show was subsequently canceled.
