That plane is MD- 1 1, that is, McDonnell Douglas 1 1, and its flight number is 2 173 (the flight number is equivalent to the license plate of the car, and this number will follow this plane until it is scrapped, and it must not be used by other planes after it is scrapped).

1September 1998 10, 19: 38, China eastern airlines flight MU586 from Shanghai to Beijing took off, with captain ni, co-pilot Yan Baodi, mechanic and * * * member of the communist youth league.

Operator Lu Ge cooperated closely, and McDonnell Douglas-1 1 with the registration number of B-2 173 quickly merged into the night sky. When Ni closed the landing gear, he found that the red signal light of the front landing gear did not go out, indicating that the front landing gear was not closed. When the plane rose to 900 meters, Ni made another landing gear retraction action according to the checklist procedure, only to see the red signal light still flashing. Ni realized the seriousness of the plane fault, decided to return after obtaining the consent of the controller of Hongqiao airport tower, and informed Xu Huanju, the flight attendant who was busy in the cabin.

With the consent of the tower controller of Hongqiao Airport, Ni will take the way of "throwing" in the air. Completed a set of sudden ascent, sideslip and steep slope hovering movements, but the centrifugal force failed to "throw" the front wheel down.
