La preuve manquante: Nevada Triangle

SYNOPSIS

Documentary examining theories as to why there have been so many apparently unexplained air crashes in America's Sierra Nevada mountain range. UFO expert Jeff Gonzales believes that the testing of alien technology in USAF facility Area 51 is interfering with earthbound navigation systems, while Peter Merlin also thinks that the air base is responsible, but that it is being used to assess advanced military aircraft. Climatologist Kelly Redmond believes that the geology of the Sierra Nevada holds the key as it can create freak storms, while meteorologist Zach Tolby suggests the topography and weather combine to create unpredictable downdrafts capable of causing aircraft to fall.
