At 2.14am on June 1, 2009, Air France flight 447 crashed into the Atlantic killing all 288 passengers on board making it one of the deadliest plane crashes of all time.
To this day, the fatal course of events remains without explanation despite the technical reports, the investigations even with the recovery of flight recorders from the far bottom of the ocean.
What really happened? What about the human factor? Were the problems only technical? Can this accident happen again? To what extent are we safe when we board a plane?
