Pilot error caused Argentine crash that killed French athletes

Pilot error caused a twin helicopter crash in Argentina that killed three French sports stars, five crew members and two Argentine pilots filming a reality TV show last March, investigators said today.
"The triggering factor of the accident was, according to the information obtained during the investigation and its analysis, the pilots' lack of perception of the closeness or the deficit in the separation between their respective aircrafts," Argentina's aviation investigations unit, the JIAAC, said in its report on the crash.
