Eastern Airlines Flight 401 is coming in for a landing in Miami. The crew have three green lights confirming that their landing gear is locked, but they only have two. Captain Robert Loft decides to have the auto pilot fly the plane in a holding pattern while he and his crew work to fix the problem. Flying at 2,000 feet all three crew members focus their attention on the troublesome bulb. None of them notice that the plane is slowly falling to the ground, until it's too late. The brand new L-1011 slams into the remote swamp-land of the Florida Everglades. Miraculously 77 people survive the crash. Investigators determine that the plane was mechanically sound, and it's auto pilot was working. So why had the state of the art jetliner fallen from the sky? The clues would lead investigators to a very troubling cause.

In September 2006, a newly built business jet takes off from Sao Jose dos Campos, Brazil with seven people on board. Meanwhile, a passenger jet carrying 154 people takes off from Manaus in northern Brazil. The business jet never receives confirmation from Air Traffic Control to lower its altitude according to the flight plan. From this point on the two planes are on a collision course. Both jets are clipped at the wing. The smaller jet miraculously lands with no injuries but the passenger jet nosedives into the Amazon rainforest. Find out how this disaster resulted in the improvement of on board collision avoidance systems.

In 1996, on departure of a Birgenair Flight, the pilot ignores vital information given by a junior crew member before smashing into the ocean. The data recorder reveals the confusing sound of multiple alarms. The plane was giving conflicting information as tubes that measured airspeed had been blocked by insect nests. But disaster could have been averted if the crew had heeded warning signs even before the plane lifted off.
