July 17th, 2007 TAM Airlines Flight #3054 is on its final approach to Sao Paolo's notorious Congonhas Airport. Runway 35-L at Congonhas is one of the busiest and most treacherous airports in the world. It's built on a hilltop, completely surrounded by tall buildings. The crew of Flight #3054 gets a report that the runway is wet and slippery. Captain Henrique Stephanini brings his Airbus A-320 down at the foot of the 1,945 meter long runway, activates the one working reverse thruster and applies the brakes, but his plane doesn't slow down. It hurtles down the runway at top speed, crosses a highway and slams into a building and adjacent gas station. No one on the plane survives. Twelve people on the ground are also killed.

To solve this issue the pilots drop down to a lower altitude, but before they can reach it a Stall Warning fills the cockpit. The plane is flying too slowly to remain airborne. Before the pilots can figure out what has caused the problem, the aircraft drops from the sky and crashes on a remote Venezuelan farm. By far the worst aviation disaster in the country's history, a small team of Venezuelan investigators must now determine what brought down one of the safest airplanes in the world.

En route from Cairo, the DC-8 eventually touches down for a routine refueling stop in Gander, Newfoundland. But just seconds after taking off again for the last leg of its journey, the plane immediately loses airspeed and altitude and crashes into a heavily wooded area just outside the remote Canadian town. An unprecedented disaster, it is one of the deadliest aviation accidents of all time and the resulting investigation ignites a storm of controversy that continues to this day.

Dropping thousands of feet in mere seconds, there is a massive explosion as the aircraft crashes into a farmer's field. All 14 people on board die in the disaster, and the impact is so violent that the wreckage is not recognizable as an airplane. Investigators first suspect there was a bomb on board, but when the theory is dismissed, they dig deeper and eventually reveal a chilling story of good intentions gone horribly wrong.
