The horrifying incident happened in May, the publication reports, when a small twin-engine medevac aircraft carrying two pilots and two medical workers departed from Roswell, New Mexico. Heading West for the small mountain village of Ruidoso, the crew became the victim of an electronic warfare exercise being conducted at the nearby White Sands Missile Range, a test which rendered their navigational system inoperable.

Due to a combination of low visibility and an air-traffic control that was stretched far beyond capacity — at least three other planes reported navigation disruptions due to the GPS jamming — the pilots failed to register a mountainous formation between their plane and the landing strip.
