Changes

KAL 007's nose begins to pitch up immediately (Plot 1, line 2) to be followed by a more gradual increase in altitude (Plot 1, line 1).  These changes appear on the crew's instruments.  They may also have sensed them.  Immediately upon missile detonation, the jumbo jet begins to experience buffeting (yawing) as the dual channel yaw damper is damaged (Plot 2, line 6).  Yawing would not have occurred if either No. 1 or No. 2 hydraulic systems were fully operational.  What does not happen that should have happened is that the control column (Plot 1, line 3) does not thrust forward upon impact (it should have done so, as the plane was on autopilot—plot 2, line 8 -- to bring down the plane to its former altitude of 35,000 feet).  This failure of the autopilot to correct the rise in altitude indicates that hydraulic system No. 3, which operates the autopilot actuator, a system controlling the plane's elevators, was damaged or out.  KAL 007's airspeed (Plot 1, line 4) and acceleration rate (Plot 1, line 5) both begin to decrease as the plane begins to climb.

'''At 18:26:06''', Capt. Chun yells out, "What happened?"  First Officer Son responds, "What?"  Two seconds later, Chun yells, "Retard throttles."  Son responds, "Engines normal, sir."  (This indicates that Maj. Osipovich's heat seeking missile has missed its mark.)  KAL 007 continues its climb (it will do so until it reaches 38,250 ft. in altitude—Plot 1, line 1) when at twenty seconds after missile detonation a click is heard in the cabin—which is identified as the "automatic pilot disconnect warning" sound.  Pilot or co-pilot has disconnected the autopilot and is now manually thrusting the control column forward (Plot 1, line 3) in order to bring down the plane.  But we see that though the autopilot has been turned "off" (Plot 2, line 8), manual mode will not kick in for another twenty seconds (Plot 2, line 9).  This failure of manual to engage upon being commanded indicates again, failure in hydraulic systems No. 1 and No. 2.  But there is progress, of sorts!  Though still rising in altitude, with the thrusting forward of the control column, KAL 007's nose begins to come down.  That is, pitch is being corrected (Plot 1, line 2).  Nevertheless, Capt. Chun absorbed with the danger of the rising altitude, calls out, "Altitude is going up!... Altitude is going up!" '''(18:26:22 and 18:26:24)'''  But immediately another problem presents itself.
