Of course I've seen the video, a number of them from different angles. The pilot was extremely lucky to escape. Seems to me that the main strop ended up in the main rotor after the load was probably already earthed by ground contact. It also appears that a longer strop might have prevented the problem.
I don't actually understand your point about the earthing strop or why you're asking about my personal USL experience.
No I wasn't on the same USL course as this pilot. My instruction predates the pilot's experience by about fifteen years and was given by the RAF. We flew quite a lot of varied USLs on the squadrons in days gone by. I latterly also used to instruct USLs on an RAF SH OCU and flew JATE USL trials on a number of occasions.
And you?
