40' from a cliff?
Review the tape at 0:19 mark and the nose gear is approx. 8' past the end of the threshold paint.
0:39 shows a bus that appears to be on the runway in front of the a/c.

Maps.google shows approx. 200-300' displaced thresholds with no paint markings.
Based on that I estimate the distance to the end of the pavement to be greater than 40' and more likely 200-300'.
Close call.
