All of this has been discussed already.
No winch was present so they couldn't haul him in. They cannot just grab unto the rope obviously and physically pull him in cos they aren't strong enough and they cannot reach it.
There were ppl asking why was the paratrooper grabbing unto his helmet like he doesn't want to lose it. He is signaling to the dive master he is aware of the situation and that is to cut off the line and he will use his emergency chute which didn't open in this case and i heard he landed on someone's gate impaled. This jump took place at chiang mai and it's an annal jump for some children's celebration.
