           In 1998, a modern airliner owned by one of the world's best airlines took off from the east coast of Canada. At the height of 10000 meters the plane caught fire. For 6 minutes before the explosion, the connection with the pilots was interrupted. Then the plane crashed into the ocean. Killed 229 people. The cause of the fire was unknown. Аviakatastrofy video investigation you can look below at our site.


            2 September 1998, the 111 flight was preparing to fly from New York International Airport. Kennedy to Geneva. Aircraft MD-11 - modern airliner was built in 1986. This is one of the most reliable jet aircraft. Urs Zimmermann was in command of the crew. The co-pilot is Stefan Loew. A calm business atmosphere reigned in the cockpit. Onboard there were 215 passengers and 14 crew members. Most of the passengers were French, Americans and Swiss.


            In 20: The 18 airliner broke away from the runway and headed northeast towards the Atlantic. The first 15 minutes after takeoff, there was no connection with the 111 board. The air route across the Atlantic was controlled by an air traffic control center located in the small town of Moncton. For the first time, Captain Zimmerman contacted the dispatcher only half an hour after takeoff. Pilots prepared for a standard transatlantic flight. In the MD-11, for the first time in the world, entertainment devices were installed. Passengers were offered movies, games and news programs. Undoubtedly, this innovation attracted customers of the airline. However, it soon led to disaster.


            After a while, the pilots smelled smoke. The co-pilot immediately got up and inspected the cabin ventilation system. He did not notice anything unusual. He did not even suspect that danger was lurking behind the panel.


            22: 13. The pilots did not have time to calm down, as smoke appeared in the cabin again. Following the instructions of the airlineSwissair"The captain decided to land the aircraft at the nearest airport. He contacted air traffic control in Moncton and signaled «pan-pan-pan». Pilots are urgently needed to make an emergency landing.

Expert: Signal "pan-pan-pan"- International call sign, which is used to attract the attention of air traffic controllers for an emergency before to signal distress.


            The captain wanted to land in Boston, and the controller gave the go-ahead. Also, the rescue center in Boston was warned about flight 111. The dispatcher determined that the plane was 122 kilometers from Halifax and 556 kilometers from Boston. But pilot Zimmermann chose an airport he knew.


Expert: When there is an emergency, pilots prefer to land at the airport familiar. So it is easier to overcome stress. So it was at that time. When smoke appeared in the cockpit, the captain started to think about where the nearest big airport, where you can find out everything with the mechanic. The answer is obvious - Boston.


            One minute has passed since the callsigns "pan-pan-pan". After assessing the situation, Captain Zimmerman agreed to land in Halifax. He changed course and continued to decline. The pilots said they needed time to get the plane ready for landing. Apparently they wanted to clean up the cabin. Therefore, the dispatcher decided that the situation was not critical. At this time, the captain of board 111 was filling out the flight sheet. It took him almost 20 minutes.


            5 minutes after the call. The dispatcher has instructed to descend to the height of 1000 meters. However, pilots are again told that they need time to put in order the passenger compartment.


Manager: From my perspective, it looked quite easy. I decided that the board is taking all the necessary measures. I was sure that they sit safely in Halifax.


            The plane stopped descending and flew at an altitude of 6000 meters. They flew up to Halifax, where they had already prepared a landing strip. Captain Zimmerman took some time to study the airfield of the airport. At this time, the senior steward told the passengers that the plane had changed course. There were no signs of smoke in the cabin, so the passengers calmly accepted this message. The dispatcher reported that 50 kilometers remained before Halifax. This was too little. The 111 flight was at an altitude of 6 kilometers and could not land so quickly.


            7 minutes after the call. Ground services were preparing to take the plane. Making a U-turn and dropping near Halifax, the pilots reported that they need to lose more than 200 tons of fuel. Manager was amazed!


Manager: At this point, the situation is very difficult. After that, I got more and more disturbing information.


            He tried to steer the plane in such a way that he did not move far from Halifax. Fuel dumping is a common procedure. If you do not reset it, the plane could explode when landing. The pilots chose to dump fuel into the water and flew to the bay. This once again convinced the dispatcher that everything was under control on board.

            10 minutes after the call. The cockpit was filled with smoke. At the height of 3000 meters, the autopilot turned off for the pilots. The fire got close to the controls, and that was just the beginning. Onboard we have failed all control systems. Soon, the pilots left the tranquility. They began to send a distress signal. Pilots started talking at once. The noise and interference prevented the manager to understand the main thing: Loew said that the plane needed to land immediately.


Manager: It's hard to explain the feelings that overwhelmed me. I replayed a thousand times in my head all the events of that terrible night. Maybe I've done? Maybe I made a mistake somewhere? In the end I realized that I did everything that depended on me.

            30 seconds after the distress call, the cockpit turned into hell. All screens went out, fire raged. There was no longer a connection with an airliner in distress. After 6 minutes, the coastline heard a deafening explosion. These 6 minutes with the plane had no connectionAnd no one knew what had happened.


Manager: It's hard to convey the feeling of helplessness that I felt then. I could not do anything. Just I sat and waited. I was hoping that they will turn back to the airport, but it did not happen.


            3 September 1998 of the year. In the morning, the search team collected the terrible remains of the flight 111. All who were aboard perished.


            The Canadian Passenger Transportation Department launched the largest investigation in the country's history. It was clear that there was a fire in the cockpit, the dead liner. But why?


Investigator: We had to have a very serious investigation. First of all, we needed to raise the plane at a depth of 50 meters. As it turned out, It lays at the bottom of a 2 million small fragments. And among them we have to find those that have helped to understand what happened on board.


            A complex phased plan was developed. First of all, the divers examined the wreckage. They found out that the plane literally crashed to smithereens. Soon the weather worsened and they had to suspend their underwater work. At this rate, the investigation could have been going on for years. On September 12, the US Navy provided remotely controlled vessels that could conduct more thorough searches. Thanks to them, they managed to study well the place of the crash of the liner. Good luck soon came. "Black boxes" were found among the wreckage. Cockpit recordings and computer data indicated that all systems on board were operating normally. The failure occurred only a few minutes before the disaster.


Investigator: According to the parametric recorder, the aircraft was actually serviceable. Also smoke in the cockpit everything else was in order. When the plane started to decline, suddenly one after the other systems began to fail.


            However, the flight recorders did not show how and where the fire started. At this time, the barges were combing the seabed and retrieving the wreckage of the aircraft. Then in the hangar organized a laboratory in which experts could investigate the wreckage. Delivered debris carefully sorted into categories. Investigators had to solve one of the most difficult puzzles in aviation history. How did it happen that a small fire in the cabin led to a catastrophe?

            Investigating the 250 kilometers of wiring, investigators found out that fire was caused by a short circuit. The source of ignition was right behind the copilot's seat. The first suspect immediately became a new entertainment system.


Expert: The system was still very imperfect. It consumed a lot of energy, and because it worked constantly, it quickly overheated. There was no switch to turn it off. Moreover, the cooling system was not provided either.


            Even when the pilots, preparing for an emergency landing, turned off the lights in the cabin, the entertainment system continued to work. Swissair immediately seized entertainment systems from all its aircraft. However, the investigators did not finish their work on this. They believed that only overheating in the entertainment system could not lead an 111 flight to a catastrophe.


            November 4 1998 of the year. The search for the causes of fire continued. The experts found out that the invisible fire had spread from the cockpit to the first class cabin. Under the skin is actively burning wiring. It was also clear that the pilots did not act fast enough. They were too executive and meticulous.


Expert: In case of danger they needed as quickly as possible to land the plane, and then to fill the flight plan. We had to throw away all that prevented the landing.

            But a careful study of the timing revealed that in those conditions the plane still could not land at Halifax airport. They simply would not have enough time. When the problem was discovered, they were at an altitude of 9000 meters. To fly to the ground, they needed 13 minutes. The pilots did not have this time. Whatever the cause of the fire, the fire broke out instantly. The disaster was inevitable.


            September 1999 of the year. After a year of costly research and investigation, the investigators found out something. It was found that the wiring where the short circuit occurred was close to the flammable material. From this material was made insulating coating, which was used in civil aviation around the world. According to the results of the tests, this material belonged to the group of poorly-flammable, fast-extinguishing materials. Investigators subjected this insulating material to new tests.


Expert: Amazingly, it turned out that it is flammable, combustible material!


            The commission of inquiry concluded that it was necessary to tighten the requirements for the materials used for the construction of passenger aircraft. The answer was found. The fire started in the wiring located behind the cab. From the sparks caught fire insulation, and from there the fire spread to other materials such as plastic and foam. The fire spread with incredible speed. After a 14 minutes after the distress signal was given, the flame will de-energize the instruments in the cockpit. Pilots until recently tried to land the plane. However, no instrument, he was not controllable and with terrible force fell into the water. Сmotret online plane crash passenger planes above.


            The 4,5 of the year and 40 million dollars were spent on the investigation. It was the biggest investigation in the history of Canada. It has been put forward new requirements for the materials used in aircraft construction. The company «Swissair» Remove all flammable materials from their aircraft. There was also changed the procedure for filling in flight plan. Now, pilots have more time to assess the situation of flight. All this was done in order to never repeat the tragedy that befell flight 111.
