Incidents that changed history ... the doomed flight 447

We will start on June 1, 2009 with a series of events that changed history and that will interest contemporary history, and I hope you like it.


 Today I will take you to the incident of the crash of the French plane (Flight 447), which was on its way from Brazil to France. Her downfall was due to a fatal error on the part of the co-pilot, in addition to bad luck, as well as the captain's misbehavior. But first, I must list the crisis from its inception. First, the plane was so advanced that it was said that it could fly on its own thanks to the highly advanced autopilot system,,, 

As for the pilots, their role is limited to taking off and landing The plane took off safely from Brazil and flew without any problem over the Atlantic Ocean And after two hours of flying, the captain decided to go to rest in a special room and called the second co-pilot to take over his duties (even though the plane started to get into a storm and we don't forget that the plane flies automatically).

 ...just minutes after the captain left, the storm intensified and some pieces of ice entered the plane's sensors that give information about the plane's speed, altitude, etc. and here the problems begin.. Due to a failure in the plane's sensors, the autopilot system was canceled and switched to the manual flight system, and Cédric Bonin took over that task and this is the first mistake, because he is the least experienced of his colleague David Robert . 

And since the plane's sensors failed, it gave wrong information but The pilots did not realize this, and among that misinformation was that the altitude had dropped, so pilot Cédric Bonin raised the nose of the plane to a height of more than 11,500 metres, and here the disaster occurred as the plane entered a stall and free fall (where the plane's engines could no longer propel it forward due to the high altitude, which means the loss of the speed required to fly) and thus enters a free fall position, but in a semi-horizontal shape To get out of this situation, the following maneuver must be performed: lower the front of the plane slightly to gain the speed required for flight, and then climb again 4 minutes before the plane crash, the captain was called for help, but what everyone didn't know was that Cédric Bonin kept raising the nose of the plane the whole time, which impeded his exit from Stall position, and, one minute before the crash, the captain realized the fatal error he had made His colleague told him to lower the front of the plane to gain speed again, but it was too late, the plane was only 3 kilometers above the ocean surface, and therefore impossible to survive.

 If we summarize the causes of this tragedy, we will find: 

 The captain's choice of an inappropriate time to rest (as the plane entered a tropical storm) The less experienced pilot assumed responsibility for manual flight, and here we are talking about Cédric Bonin Misunderstanding and communication between the pilots, David Robert did not know what Cédric Bonin had done by raising the front of the plane for more than 10 minutes, which caused the plane to lose the required speed But I see an additional reason, which is the lack of training and the pilots' heavy reliance on the autopilot system, which made them make "stupid" mistakes that are not worthy of a professional pilot. What are your opinions and what are the lessons learned?
