Unregistered - in order for the tag line (we call it a hi-line) to be effective, it needs to either be attached to one end of the stretcher or attached to the aircraft hook and then routed through the end of the stretcher.
The other important factor is that the person on the ground has to know how to use the line to prevent a spin.
There was one attached initially but in the middle of the stretcher so it would be very ineffective in preventing, let alone controlling, the spin.
As I have said before - everyone thinks winching looks soooo easy - right up until it goes wrong because you weren't trained properly or didn't practice the skills.
You can see the crew chief doesn't have a scooby about what to do - he sticks his foot out to try and stop the stretcher spinning FFS.
The crew should have been very ashamed of that press conference.
