The chill fact: a functioning aircraft with running engines and a living crew flew straight into a mountain with its terrain warning system disabled - three separate times - and the cockpit voice recorder preserved every word. How did a twin-engine Twin Otter, built for these valleys, end up at 14,500 feet in snowfall with no mechanical failure to blame?
In this episode, we lay out the sequence of departures, weather reports, crew decisions and the moment-by-moment cockpit audio that led to the crash, and we ask how a system designed to prevent controlled flight into terrain ended up turned off before the aircraft ever left the ground.
