The captain on duty was seated at the right side of the plane and his co-pilot, who was at that time training for promotion to be a captain, was sitting on the left seat. A few moments later, the captain signals an SOS on the transponder and suggests that the flight return to Tokyo. The airplane went down to cardinal twain thousand feet and went on doing violent movements the plane, for about two minutes was doing a Phugoid, or longitudinal motion and rolls. The captain and his co-pilot were helpless and had no means in controlling the airplanes heading through the usual flight control inputs. Their only focusing of limited c ontrol is done through thrust differentials. The plane was able to maintain an altitude of twenty two thousand feet and two hundred and fifty knots for an approximate duration of twenty minutes.At around 639 in the evening, the main landing gear was deployed which caused the erratic movements of the plane to intensify. The plane then did a controlled turn to the left while descending to eight thousand feet. Erratic movement of the plane meanwhile, continue.

Boeing, as owners of the plane, are somehow responsible for the crash alone definitely they are not the only ones to blame and do not deserve to be goddamned in entirety.Part of the responsibility lies with Japan Airlines who maintains the plane. In fairness to Boeing, they have provided specific repair book of instructions to the plane that was not followed by those who were responsible for the repairs. The plane had previously suffered damage to the bulkhead in 1978 but was not repaired properly. As stated in the report, The initiation and propagation of the weary cracks are attributed to the improper repairs of the bulkhead, conducted in 1978, and since the fatigue cracks were not found in the later maintenance inspection, this contributed to the accident. (Aviation Safety Network, 2008). Boeing did its part by providing proper instructions but t heir failure to see to it that they were carried out properly contributed to the crash which makes them partly guilty of neglect. There was mental confusion on the rescue operation, A US owned helicopter was the first at the scene, about twenty minutes after impact. The US chopper in turn, informed Yokota Air Base and offered backup. only when the US helicopter was ordered to return to base because Japanese forces were to handle the mission.Poor visibility at the crash site prompted the Japanese team to report that in that location were no survivors and made it impossible to land. Thinking that there were no survivors the rest of the rescue team waited till the next morning to check out the site. But there were survivors, reports show that injuries on the bodies found imply that they survived the crash but were not given warm medical attention which caused their deaths.If the helicopter pilot hadnt reported abruptly that there were no survivors, there could have been.
