Double thumbs up signals clear of all ground obstacles in this operation, 1 thumb up clear to ascend. Actually has nothing to do with putting on a show. For the record it was the crewmans first operational winch, with no other on ground assistance, and a patient who was 2 km from the nearest road, initially refusing to be winched. The banter regarding this tragedy I find pretty heartless in the absence of any official reporting. Pretty easy to chuck in apples from the sidelines when you're not involved.
