Why does the skier not see the boarder until the last minute?....I thought the same thing every time I watched it. Why is the skier not reacting? He seems to be competent. My thought is that he was just lost in his own reverie enjoying the pow nand zen and was just not keeping an eye out for his boarder buddy.....
His helmet cam is pointed down - the leading edge of his helmet, his full torso including upper chest, his legs and feet are all visible in the video - which seems to indicate his head is pointed down. He might not have seen his friend at all until it was too late because he was looking down.
He might have set the angle of the camera to point down, but I think this is unlikely.
