Full episodes included are: 0:00 Season 4 Episode 5 "Hidden Danger": Around the globe, more than six billion people have travelled on a Boeing 737. They’re the backbone of the aviation industry. But in 1991, something happened onboard a 737 that sent shudders through the world of aviation. Moments from landing, United Airlines 585 starts spinning out of control and falls out of the sky at 450 kilometres per hour. Everyone on board is killed. In ten violent seconds, the crash site has become one of the most mysterious air disasters in aviation history. Almost two years after the crash, the NTSB had studied thousands of pieces of evidence – but they can’t solve the mystery. On September 7, 1994, a year after the undetermined report on Flight 585 is released, the killer strikes again. Another 737 – this time US Air 427 – crashes near Pittsburgh. All 132 passengers and crew are killed. Investigators begin to quickly see some striking similarities between US Air 427 and the unsolved case of United 585. With two crashes just a few years apart, serious questions are now being raised about the safety of 737s around the world. Billions of dollars, perhaps the airline industry itself, are at risk. Investigators need a break in the case and fast. 50:26 Season 4 Episode 2 "Falling From The Sky": On a clear summer night, during a seemingly calm trip to Australia, the impossible happens to British Airways Flight 009. Smoke starts filling the cabin. The engines catch fire – then stop working. The flight crew witness a bizarre shower of brilliant sparks strike the windshield of the aircraft. The entire plane is surrounded by a shimmering white glow. Without power, the plane begins falling from the sky. Passengers are terrified. The crew have no idea why their engines have quit – or how to get them working again. As they fall through the night the captain faces a difficult choice – return to the nearest airport and likely crash into the mountains, or attempt an incredibly difficult ocean landing. Just minutes before crashing into the sea, the stricken plane’s engines roar back to life. The jet limps back to Halim airport in Jakarta. But the crew realises that their windshield is severely damaged -- making it nearly impossible to see their runway. After suffering through a night of bizarre twists and turns, they manage to touch down safely at Halim. But they are still bewildered – what had knocked their plane from the sky? What investigators discover changed the way pilots are trained and altered the understanding of how volcanoes can affect aviation. 1:40:44 Season 5 Episode 8 "The Plane That Wouldn't Talk": February 6, 1996, a group of German tourists in the Dominican Republic are waiting impatiently to board their flight to Frankfurt. The plane is grounded due to mechanical problems and the airline is forced to substitute the original aircraft with a Boeing 757 owned by Birgeniar. As flight 301 accelerates for take-off, the flight's captain notices that his airspeed indicator doesn't match his First Officer's gauge. Within moments, the plane's computer starts bombarding the cockpit with confusing alarms and the pilot hears a warning that he's suddenly flying too slowly. Flight 301 begins to fall from the sky, losing altitude and spinning wildly out of control. The crew sadly never regain control of the plane and less than five minutes after takeoff, it slams into the Atlantic Ocean and all 189 passengers on board are killed.
