According the report the autopilot disengaged and stall warning engaged at 2 hours 10 minutes and 5 seconds into flight. Less than 2 minutes later the recorded speeds became invalid. At 2 hours 14 minutes and 28 seconds, the recording stopped. The final vertical speed was recorded around 10,912 ft/min.
Thus mathematics may be defined as the subject in which we never know
what we are talking about, nor whether what we are saying is true.
