What I find odd, at about 25sec in the youtube video above it is quite clear what is coming. Why did he freeze up and go straight? I know hindsight is 20/20 but if you know there are cliffs around, I'd have tried to put it down at least or something idk.
In fact even from around 10 sec you can see the ground dropping away ahead. If it is clear on the video, wonder how he didn't notice it.
