Right after they run out of the stall, you can easily see one or two men in the stall - they're either holding the stall up against the wind of the helicopter or they're there for some other unexplainable reason.
Suggested correction: I have viewed this several times you have mistaken the boom mic for a large round tree branch.
It looks nothing like branch. This is a real boom mic.
