(1)- a collision between a passenger plane and a cargo plane in the air
(2)- all dead
(3)- Originally, two controllers were supposed to work, but the practice at the time was that one person took a break at night, so only one controller worked
(4)- But on that day, a plane was landing at an airport in his jurisdiction that didn’t usually land
(5)- But the telecommunication technicians came to check the communication on that day, so I cut off the communication line for a while
(6)- So I tried to contact the airport there, but I couldn’t get through the phone, so I’m holding on to this for a long time
(7)- But at this time, the plane and the cargo plane were crossing at the same altitude
(8)- Another control station received a collision risk alert, so I called the relevant control station 11 times, but the phone was not connected due to a communication check
(9)- The radar should also be alerted to the danger of collision, but the radar was checked that day, so the alarm didn’t come in
(10)- Air collision prevention device TCAS alarm sound on both aircraft instructs the passenger plane to rise and the cargo plane to descend
(11)But the controller, who was struggling to get through the phone at this time, belatedly discovered that the two aircraft were about to collide in the radar
(12)- So the controller instructed the plane to descend. TCAS told it to rise
(13)- However, if TCAS and controller instructions are different at the time, European guidelines follow TCAS instructions and Russian guidelines follow controller instructions
(14)- Even the controller was so distracted that he misinformed me that the plane coming from the 10 o’clock on the left was coming from the 2 o’clock on the right
(15)- I’ve been looking for it for a long time because the ferry crew says they’re coming from the right
(16)- But the captain of the plane was a veteran, and the captain was a trainee, so the captain was actually a beginner
(17)- The captain insists on a rise according to TCAS instructions, but the captain follows the controller instructions
(18)- That’s how the cargo plane descended according to TCAS instructions, and the passenger plane descended according to controller instructions
(19)- So, after the two planes collided in the air, the cargo plane lost its center of gravity, and the plane crashed in two parts in the air
(20)- As the plane’s black box was in the cockpit, the captain’s voice was recorded as he was about to die in a free fall with the lamentable boogie and fuselage after the crash
(21)- Since then, the bereaved family, who lost their daughter and wife, killed the controller
(22)- The bereaved family who killed the controller lived in prison, was treated as a hero in their hometown, and was appointed deputy construction minister
(23)Most accidents create a situation where accidents inevitably happen, but this is literally a huge event in probability
