Let’s cut right to the video description:
I was skiing when my friend gets off balance and ends up hanging from the chair. He did not have the security bar down. He hung from about Pole 8 to 21, and at 21 he fell. This was on a lift that averages 37ft above the ground, But pole 21 was the 3rd highest strech at about 45ft high, 19 being the highest. He suffered from injuries including: concussion, skull fracture, collapsed lung, and a lacerated liver.
He had to be helicoptered out to a local hospital.
So there you have it. Keep the security bar down.
Or, if you have to fall, calculate which pole is closest to the ground and fall there. Duh.
